TriMas agreed to sell its aerospace fasteners segment for an all-cash price of $1.45 billion to industrial-focused investment firm Tinicum. The price represents an enterprise value multiple of approximately 18x last twelve months (LTM) third quarter 2025 adjusted EBITDA.

City of Industry-based TriMas Aerospace designs and manufactures fasteners, collars, blind bolts, rivets, ducting and connectors for air management systems, and other machined parts and components.

With approximately $374 million in revenue over the last twelve months, TriMas Aerospace operates nine manufacturing facilities and employs 1,250 people. Brands include Monogram Aerospace Fasteners, Allfast Fastening Systems, Mac Fasteners, RSA Engineered Products, Weldmac Manufacturing, Martinic Engineering and TFI Aerospace.

The deal “represents a compelling valuation and validates the strength of the aerospace business we’ve built,” stated Herbert Parker, TriMas’ Board of Directors Chair.

“This transaction reflects the high-quality nature of the business and its continued strong momentum.”

CEO Thomas Snyder said the divestiture will make TriMas a “focused, high-margin packaging platform.”

The deal is expected to close by the end of March 2026.
