      All the shares of Common Stock of TriMas Corporation ("TriMas" or the
"Company") being offered hereby (the "Shares") are held by Richard A. Manoogian
(the "Selling Stockholder").  TriMas will not receive any of the proceeds from
the sale of the Shares.

      The Selling Stockholder (and his donees, distributees, pledgees and
personal representatives) may, from time to time, offer for sale and sell or
distribute the Shares (a) in transactions executed on the New York Stock
Exchange or other exchanges on which the Shares may be traded, (b) in negotiated
transactions or (c) through other means.  Sales may be effected at market prices
prevailing at the time of sale or at such other prices as may be negotiated by
the Selling Stockholder.

      The Selling Stockholder may effect such transactions by selling Shares to
or through dealers, and such dealers may receive compensation in the form of
underwriting discounts, concessions or commissions from the Selling Stockholder
(which compensation, if any, is not expected to be in excess of customary
commissions).  The Selling Stockholder and any dealers that participate with the
Selling Stockholder in the distribution of Shares may be deemed to be
underwriters, and any commissions received by them and any profit on the resale
of Shares sold by them might be deemed to be underwriting discounts and
commissions under the Securities Act of 1933.

      TriMas has agreed to indemnify the Selling Stockholder against certain
liabilities under the Securities Act of 1933.

      Section 145 of the General Corporation Law of Delaware empowers the

connection with any action, suit or proceeding brought or threatened by reason
of the fact that such person is or was a director, officer, employee or agent of

other entity at the request of the Company.  Article 13 of the Company's
Restated Certificate of Incorporation provides that each person who was or is
made a party to (or is threatened to be made a party to) or is otherwise
involved in any action, suit or proceeding by reason of the fact that such
person is or was a director, officer or employee of the Company shall be
indemnified and held harmless by the Company to the fullest extent authorized by
the General Corporation Law of Delaware against all expenses, liability and loss
(including without limitation attorneys' fees, judgments, fines and amounts paid
in settlement) reasonably incurred by such person in connection therewith.  The
rights conferred by Article 13 are contractual rights and include the right to
be paid by the Company the expenses incurred in defending such action, suit or
proceeding in advance of the final disposition thereof.

      Article 12 of the Company's Restated Certificate of Incorporation provides
that the Company's directors will not be personally liable to the Company or its
stockholders for monetary damages resulting from breaches of their fiduciary
duty as directors except (a) for any breach of the duty of loyalty to the
Company or its stockholders, (b) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (c) under
Section 174 of the General Corporation Law of Delaware, which makes directors
liable for unlawful dividends or unlawful stock repurchases or redemptions or

ITEM 17.  UNDERTAKINGS.

      (a)  The Company hereby undertakes:

            (1)  To file, during any period in which offers or sales are being
      made, a post-effective amendment to this Registration Statement:


                  (i)  To include any prospectus required by Section 10(a)(3) of
            the Securities Act of 1933;

                                                II-2


                  (ii)  To reflect in the prospectus any facts or events 
            arising after the effective date of the Registration Statement 
            (or the most recent post-effective amendment thereof) which, 
            individually or in the aggregate, represent a fundamental change 
            in the information set forth in the Registration Statement; and

                  (iii)  To include any material information with respect to the
            plan of distribution not previously disclosed in the Registration
            Statement or any material change to such information in the
            Registration Statement;

      provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
      information required to be included in a post-effective amendment by those
      paragraphs is contained in periodic reports filed by the Company pursuant
      to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that
      are incorporated by reference in the Registration Statement.

            (2)  That, for the purpose of determining any liability under the
      Securities Act of 1933, each such post-effective amendment shall be deemed
      to be a new registration statement relating to the securities offered
      therein, and the offering of such securities at that time shall be deemed
      to be the initial bona fide offering thereof.

            (3)  To remove from registration by means of a post-effective
      amendment any of the securities being registered which remain unsold at
      the termination of the offering.

      (b)  The Company hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Company's annual
report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
of 1934 that is incorporated by reference in the Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

      (c)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Company pursuant to the provisions referred to in Item 15 above,
or otherwise (other than the insurance policies referred to in Item 15), the
Company has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer or controlling person of the Company in
the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Company will, unless in the opinion of its counsel the matter 
has been settled
                                    II-3

 

by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in that Act and will be governed by the final adjudication of such
issue.

                                     II-4



                                SIGNATURES

Gentlemen:

      I am acting as your counsel in connection with the Registration Statement
on Form S-3 under the Securities Act of 1933, registering an aggregate of
1,440,000 shares of Common Stock, $0.01 par value (the "Shares"), of TriMas
Corporation, a Delaware corporation (the "Company").  

      I or members of my staff have examined originals or copies, certified or
otherwise identified to my satisfaction, of such documents and corporate records
as I have deemed necessary or appropriate in connection with this opinion.  

      Based upon the foregoing, I am of the opinion that:

accordance with the procedures described in the Registration Statement, will be
legally issued, fully paid and nonassessable.

      I hereby consent to the filing of this opinion as Exhibit 5 to the
Company's Registration Statement on Form S-3.
