ITEM 7. EXHIBITS.


         (c)  Exhibits.  The following exhibit is filed herewith:

         Exhibit No.  Description
         -----------  -----------
         99.1         TriMas Corporation (the "Company") visual presentation
                      titled "Fourth Quarter and Full Year 2003 Review,"
                      available at http://www.trimascorp.

ITEM 12.  RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

The Company's only public security holders are holders of its 9 7/8% senior
subordinated notes due 2012. The Company held a teleconference on February 17,
2004 reporting its financial results for the fourth quarter and year ended
December 31, 2003. Audio replay of the teleconference was accessible for at
least five business days and a copy of the visual presentation that was used for
the teleconference has been available at www.trimascorp.com.

The Company's presentation reflected an adjustment in the fourth quarter of 2003
to capitalize the value of tooling die casings on hand based on a physical
inventory of such items at two businesses in its Fastening Systems segment. This
adjustment was recorded to account for the value of such tooling assets in a
manner consistent with the Company's other businesses. In the course of
finalizing its 2003 financial statements, the Company determined, as of March
23, 2004 that capitalization of such assets would occur only for future
purchases of tooling die casings. The Company has revised its financial
information to reflect this decision, the effect of which is to reduce operating
income and Adjusted EBITDA (as defined in the presentation) by $2.2 million for
the full year and the fourth quarter of 2003. The information in the visual
presentation located on the Company's website has been revised, is attached as
Exhibit 99.1 hereto and is incorporated by reference into this Item 12. This
revised financial information also includes certain minor reclassifications made
in connection with finalizing the 2003 financial statements.
