Basis of Presentation	Jun. 30, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation TriMas Corporation ("TriMas" or the "Company"), and its consolidated subsidiaries, is a global manufacturer and distributor of products for commercial, industrial and consumer markets. The Company is principally engaged in the following reportable segments with diverse products and market channels: Packaging, Aerospace, Energy and Engineered Components. See Note 10, "Segment Information," for further information on each of the Company's reportable segments. On June 30, 2015, the Company completed the previously announced spin-off of its Cequent businesses, creating a new independent publicly traded company, Horizon Global Corporation ("Horizon"). In addition, on June 30, 2015, immediately prior to the effective time of the spin-off, Horizon paid a cash distribution to the Company of $214.5 million using the proceeds of its new debt financing arrangement and cash on hand. Consistent with previous estimates, the Company incurred approximately $30 million of one-time, pre-tax costs associated with the spin-off, of which, approximately $29 million were incurred during 2015. These costs primarily related to financing, legal, tax and accounting services rendered by third parties. Of the $30 million in costs, approximately $18 million was included in the income (loss) from discontinued operations, $9 million was capitalized as deferred financing fees associated with Horizon's debt issuance coincident with the spin-off and is included in the balance sheet of the discontinued operations and approximately $3 million relates to fees associated with the Company's refinancing of long-term debt, of which approximately $2 million was included in the income from continuing operations as debt financing and extinguishment costs and approximately $1 million was capitalized as deferred financing fees in the accompanying consolidated balance sheet. The financial position, results of operations and cash flows of the Cequent businesses are reflected as discontinued operations for all periods presented through the date of the spin-off. See Note 3, "Discontinued Operations," for further details regarding the spin-off. The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries and, in the opinion of management, contain all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of financial position and results of operations. Results of operations for interim periods are not necessarily indicative of results for the full year. The accompanying consolidated financial statements and notes thereto should be read in conjunction with the Company's 2014 Annual Report on Form 10-K.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 is currently effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, with early adoption permitted. The Company is in the process of assessing the impact of the adoption of ASU 2015-03 on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). ASU 2014-09 requires that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-09 was originally effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2016. In July 2015, the FASB issued a deferral of ASU 2014-09 of one year, making it effective for annual reporting periods beginning on or after December 15, 2017 while also providing for early adoption, but not before the original effective date. The Company is in the process of assessing the impact of the adoption of ASU 2014-09 on its consolidated financial statements.

On June 30, 2015, each of the Company's shareholders of record as of the close of business on the record date of June 25, 2015 received two shares of Horizon common stock for every five shares of TriMas common stock held. In addition, on June 30, 2015, immediately prior to the effective time of the spin-off, Horizon entered into a new debt financing arrangement and used the proceeds to make a cash distribution of $214.5 million to the Company.

Credit Agreement

During the second quarter of 2015, the Company amended its credit agreement (the "Credit Agreement"), pursuant to which the Company was able to extend maturities and resize its credit facilities following the spin-off of the Cequent businesses. The Credit Agreement consists of a $500.0 million senior secured revolving credit facility, which permits borrowings denominated in specific foreign currencies ("Foreign Currency Loans"), subject to a $75.0 million sub limit, and a $275.0 million senior secured term loan A facility ("Term Loan A Facility"). The cash distribution to the Company from Horizon was used to reduce the outstanding borrowings under the previous credit agreement.

Below is a summary of key terms under the Credit Agreement as of June 30, 2015, and the key terms of the previous credit agreement in place immediately prior to entering into the amended Credit Agreement on June 30, 2015, with term loans showing the face amount of borrowings at debt issuance and revolving credit facilities showing gross availability at each date:



Instrument	Amount ($ in millions)	Maturity Date	Interest Rate
Credit Agreement
Senior secured revolving credit facility	$500.0	6/30/2020	LIBOR^(a) plus 1.625%^(b)
Senior secured term loan A facility	$275.0	6/30/2020	LIBOR^(a) plus 1.625%^(b)

Previous Credit Agreement
Senior secured revolving credit facility	$575.0	10/16/2018	LIBOR^(a) plus 1.625%
Senior secured term loan A facility	$450.0	10/16/2018	LIBOR^(a) plus 1.625%

__________________________

^(a) London Interbank Offered Rate ("LIBOR")

^(b)The initial interest rate spread for the amended Credit Agreement is stated as 1.625%

The Credit Agreement also provides incremental term loan and/or revolving credit facility commitments in an amount not to exceed the greater of $300.0 million and an amount such that, after giving effect to such incremental commitments and the incurrence of any other indebtedness substantially simultaneously with the making of such commitments, the senior secured net leverage ratio, as defined, is no greater than 2.50 to 1.00. The terms and conditions of any incremental term loan and/or revolving credit facility commitments must be no more favorable than the existing credit facility.

The Company may be required to prepay a portion of its Term Loan A Facility in an amount equal to a percentage of the Company's excess cash flow, as defined, with such percentage based on the Company's leverage ratio, as defined. As of June 30, 2015, no amounts are due under this provision.

The Company is also able to issue letters of credit, not to exceed $40.0 million in aggregate, against its revolving credit facility commitments. At June 30, 2015 and December 31, 2014, the Company had letters of credit of approximately $22.7 million and $21.9 million, respectively, issued and outstanding.

At June 30, 2015, the Company had approximately $128.3 million outstanding under its revolving credit facility and had $349.0 million potentially available after giving effect to approximately $22.7 million of letters of credit issued and outstanding. At December 31, 2014, the Company had approximately $118.1 million outstanding under its revolving credit facility and had $435.0 million potentially available after giving effect to approximately $21.9 million of letters of credit issued and outstanding. However, including availability under its accounts receivable facility and after consideration of leverage restrictions contained in the Credit Agreement, the Company had $123.0 million and $192.0 million at June 30, 2015 and December 31, 2014, respectively, of borrowing capacity available for general corporate purposes.

Principal payments required under the Credit Agreement for the Term Loan A Facility are approximately $3.4 million due each fiscal quarter from December 2015 through September 2018 and approximately $5.2 million due each fiscal quarter from December 2018 through March 2020, with final payment of $202.8 million due on June 30, 2020.

The debt under the Credit Agreement is an obligation of the Company and certain of its domestic subsidiaries and is secured by substantially all of the assets of such parties. Borrowings under the $75.0 million foreign currency sub limit of the $500.0 million senior secured revolving credit facility are secured by a pledge of the assets of the foreign subsidiary borrowers that are a party to the agreement. The Credit Agreement also contains various negative and affirmative covenants and other requirements affecting the Company and its subsidiaries, including restrictions on the incurrence of debt, liens, mergers, investments, loans, advances, guarantee obligations, acquisitions, assets dispositions, sale-leaseback transactions, hedging agreements, dividends and other restricted payments, transactions with affiliates, restrictive agreements and amendments to charters, bylaws, and other material documents. The terms of the Credit Agreement also require the Company and its subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a maximum leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility over consolidated EBITDA, as defined) and a minimum interest expense coverage ratio (consolidated EBITDA, as defined, over cash interest expense, as defined). At June 30, 2015, the Company was in compliance with its financial covenants contained in the Credit Agreement.

The Company incurred approximately $1.8 million in fees to complete the Credit Agreement, of which approximately $1.4 million was capitalized as deferred financing fees as of June 30, 2015 and $0.4 million was recorded as debt financing fees in the accompanying consolidated statement of income during the three months ended June 30, 2015. The Company also recorded non-cash debt extinguishment costs of $1.5 million related to the write-off of deferred financing fees associated with the previous term loan.

As of June 30, 2015, the Company's Term Loan A Facility and revolving credit facility approximated fair value as the Credit Agreement was refinanced on June 30, 2015. As of December 31, 2014, the Company's Term Loan A Facility traded at approximately 99.5% of par value and the Company's revolving credit facility traded at approximately 99.2% of par value. The valuations of the Credit Agreement were determined based on Level 2 inputs under the fair value hierarchy, as defined.

Receivables Facility

The Company is a party to an accounts receivable facility through TSPC, Inc. ("TSPC"), a wholly-owned subsidiary, to sell trade accounts receivable of substantially all of the Company's domestic business operations. During the second quarter of 2015, the Company amended the facility to remove the Cequent businesses and to reduce the committed funding from $105.0 million to $75.0 million, with no other significant changes to the facility.

Under this facility, TSPC, from time to time, may sell an undivided fractional ownership interest in the pool of receivables up to approximately $75.0 million to a third party multi-seller receivables funding company. The net amount financed under the facility is less than the face amount of accounts receivable by an amount that approximates the purchaser's financing costs. The cost of funds under this facility consisted of a 3-month LIBOR-based rate plus a usage fee of 1.00% and 1.15% as of June 30, 2015 and 2014, respectively, and a fee on the unused portion of the facility of 0.35% as of June 30, 2015 and 2014.

The Company had approximately $60.3 million and $78.7 million outstanding under the facility as of June 30, 2015 and December 31, 2014, respectively, and $0.1 million and $1.6 million, respectively, available but not utilized. Aggregate costs incurred under the facility were approximately $0.3 million for each of the three months ended June 30, 2015 and 2014, and $0.5 million and $0.6 million for the six months ended June 30, 2015 and 2014, respectively, and are included in interest expense in the accompanying consolidated statement of income. The facility expires on October 16, 2018.

The cost of funds fees incurred are determined by calculating the estimated present value of the receivables sold compared to their carrying amount. The estimated present value factor is based on historical collection experience and a discount rate based on a 3-month LIBOR-based rate plus the usage fee discussed above and is computed in accordance with the terms of the agreement. As of June 30, 2015, the cost of funds under the facility was based on an average liquidation period of the portfolio of approximately 1.6 months and an average discount rate of 1.8%.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

In December 2012, the Company entered into an interest rate swap agreement to fix the LIBOR-based variable portion of the interest rate on its Term Loan A Facility at 0.74%, beginning February 2013. The interest rate swap amortizes with the Term Loan A facility payments and as of June 30, 2015 the interest rate swap had a total notional amount of $151.3 million. The interest rate swap expires on October 11, 2017, and at inception the Company designated the swap agreement as a cash flow hedge.

As of June 30, 2015 and December 31, 2014, the fair value carrying amount of the Company's derivative instrument is recorded as follows:



		Asset / (Liability) Derivatives
	Balance Sheet Caption	June 30, 2015			December 31, 2014

The following tables summarize the income recognized in accumulated other comprehensive income ("AOCI"), the amounts reclassified from AOCI into earnings and the amounts recognized directly into earnings for the three and six months ended June 30, 2015 and 2014:



	Amount of Income Recognized in AOCI on Derivative (Effective Portion, net of tax)					Amount of Loss Reclassified from AOCI into Earnings

Derivatives designated as hedging instruments
Interest rate swap	$	150	$	680	Income from discontinued operations	$	(220	)	$	(250	)	$	(440	)	$	(490	)

Over the next 12 months, the Company expects to reclassify approximately $0.3 million of pre-tax deferred losses from AOCI to interest expense as the related interest payments for the designated interest rate swap are funded.

The fair value of the Company's derivatives are estimated using an income approach based on valuation techniques to convert future amounts to a single, discounted amount. Estimates of the fair value of the Company's interest rate swap use observable inputs such as interest rate yield curves. Fair value measurements and the fair value hierarchy level for the Company's assets and liabilities measured at fair value on a recurring basis as of June 30, 2015 and December 31, 2014 are shown below.

Commitments and Contingencies

Asbestos

As of June 30, 2015, the Company was a party to 1,086 pending cases involving an aggregate of 6,967 claimants alleging personal injury from exposure to asbestos containing materials formerly used in gaskets (both encapsulated and otherwise) manufactured or distributed by certain of the Company's subsidiaries for use primarily in the petrochemical refining and exploration industries. The following chart summarizes the number of claimants, number of claims filed, number of claims dismissed, number of claims settled, the average settlement amount per claim and the total defense costs, exclusive of amounts reimbursed under the Company's primary insurance, at the applicable date and for the applicable periods:



	Claims pending at beginning of period	Claims filed during period	Claims dismissed during period	Claims settled during period	Average settlement amount per claim during period		Total defense costs during period
Fiscal Year Ended December 31, 2014	7,975	210	155	38	$	18,734	$	2,800,000
Six Months Ended June 30, 2015	7,992	173	1,187	11	$	13,505	$	1,559,705

In addition, the Company acquired various companies to distribute its products that had distributed gaskets of other manufacturers prior to acquisition. The Company believes that many of its pending cases relate to locations at which none of its gaskets were distributed or used.

The Company may be subjected to significant additional asbestos-related claims in the future, the cost of settling cases in which product identification can be made may increase, and the Company may be subjected to further claims in respect of the former activities of its acquired gasket distributors. The Company is unable to make a meaningful statement concerning the monetary claims made in the asbestos cases given that, among other things, claims may be initially made in some jurisdictions without specifying the amount sought or by simply stating the requisite or maximum permissible monetary relief, and may be amended to alter the amount sought. The large majority of claims do not specify the amount sought. Of the 6,967 claims pending at June 30, 2015, 148 set forth specific amounts of damages (other than those stating the statutory minimum or maximum). Below is a breakdown of the amount sought for those claims seeking specific amounts:

Compensatory & Punitive

Compensatory Only

Punitive Only

Range of damages sought (in millions)

$0.0 to $5.0

$5.0 to $10.0

$0.6 to $5.0

$5.0+

$0.0 to $2.5

$2.5 to $5.0

$5.0+

Number of claims

142

In addition, relatively few of the claims have reached the discovery stage and even fewer claims have gone past the discovery stage.

Total settlement costs (exclusive of defense costs) for all asbestos-related cases, some of which were filed over 20 years ago, have been approximately $7.5 million. All relief sought in the asbestos cases is monetary in nature. To date, approximately 40% of the Company's costs related to settlement and defense of asbestos litigation have been covered by its primary insurance. Effective February 14, 2006, the Company entered into a coverage-in-place agreement with its first level excess carriers regarding the coverage to be provided to the Company for asbestos-related claims when the primary insurance is exhausted. The coverage-in-place agreement makes asbestos defense costs and indemnity coverage available to the Company that might otherwise be disputed by the carriers and provides a methodology for the administration of such expenses. Nonetheless, the Company believes it is likely there will be a period within the next one or two years, prior to the commencement of coverage under this agreement and following exhaustion of the Company's primary insurance coverage, during which the Company will be solely responsible for defense costs and indemnity payments, the duration of which would be subject to the scope of damage awards and settlements paid.

Based on the settlements made to date and the number of claims dismissed or withdrawn for lack of product identification, the Company believes that the relief sought (when specified) does not bear a reasonable relationship to its potential liability. Based upon the Company's experience to date, including the trend in annual defense and settlement costs incurred to date, and other available information (including the availability of excess insurance), the Company does not believe these cases will have a material adverse effect on its financial position and results of operations or cash flows.

Claims and Litigation

The Company is subject to other claims and litigation in the ordinary course of business which the Company does not believe are material. In addition, a claim was recently made against the Company by a competitor alleging false advertising where, although no formal demand was made, the Company believed the competitor may be seeking in excess of $10 million. During the second quarter of 2015, the Company resolved the matter for approximately $2.8 million, inclusive of attorney fees and expenses.

The Company does not believe claims and litigation will have a material adverse effect on its financial position and results of operations or cash flows.

Restricted Shares

The Company awarded the following restricted shares during the first half of 2015:


•	granted 1,300 restricted shares of common stock to certain employees that are subject only to a service condition and vest on the first anniversary date of the award so long as the employee remains with the Company.


•	granted 174,874 restricted shares of common stock to certain employees which are subject only to a service condition and vest ratably over three years so long as the employee remains with the Company;

•

granted 35,813 restricted shares of common stock to certain employees which are subject only to a service condition and vest on the first anniversary date of the award. The awards were made to participants in the Company's short-term incentive compensation plan ("STI"), where all STI participants whose target annual award exceeds $20 thousand receive 80% of the value in earned cash and 20% in the form of a restricted stock award upon finalization of the award amount in the first quarter each year following the previous plan year; and


•	granted 26,704 restricted shares of common stock to its non-employee independent directors, which vest one year from date of grant so long as the director and/or Company does not terminate their service prior to the vesting date.

In addition, the Company issued 2,759 shares related to director fee deferrals. The Company allows for its non-employee independent directors to make an annual election to defer all or a portion of their directors fees and to receive the deferred amount in cash or equity. Certain of the Company's directors have elected to defer all or a portion of their directors fees and to receive the amount in Company common stock at a future date.

During 2012, the Company awarded performance-based shares of common stock to certain Company key employees which were earned based upon the achievement of two performance metrics over a period of three calendar years, beginning January 1, 2012 and ending on December 31, 2014. Of this award, 75% of the awards were earned based upon the Company's earnings per share cumulative average growth rate over the performance period. The remaining 25% of the grants were earned based upon the Company's cash generation results. The Company attained 70.25% of the target on a weighted average basis, resulting in a reduction of 28,205 shares during the first quarter of 2015.

Information related to restricted shares at June 30, 2015 is as follows:



	Number of Unvested Restricted Shares		Weighted Average Grant Date Fair Value		Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value
