U.S.-based TriMas Corp. has entered into a definitive agreement to sell its aerospace segment to an affiliate of Tinicum L.P. for $1.45 billion.
A press release said that the sale marks a significant shift for TriMas, which has been actively evaluating strategic options to streamline its business portfolio. The Aerospace segment generated approximately $374 million in revenue over the past 12 months and includes nine manufacturing facilities and roughly 1,250 employees.
Fasteners are estimated to account for 60 to 70% of the segment’s revenue, underscoring their central role in the business. Per Precedence Research, the global aerospace fasteners market is expected to expand from $7.85 billion in 2025 to approximately $15 billion by 2034.
TriMas Aerospace supplies highly engineered fasteners and precision-machined components for mission-critical applications across commercial and defense aviation markets. Its brands include Monogram Aerospace Fasteners, Allfast Fastening Systems, Mac Fasteners, TFI Aerospace, RSA Engineered Products and Weldmac Manufacturing Co., among others. The company’s products have supported programs such as the U.S. Air Force’s T-7A Red Hawk training jet.
The deal will allow TriMas to focus its resources on higher-growth and more profitable operations, including its packaging and specialty products platforms. Post-transaction, TriMas plans to invest further in its remaining segments, aiming to expand market share and enhance operational efficiency. TriMas executives said that the transaction is expected to close in early 2026.
“This agreement represents a compelling valuation and validates the high-quality nature of the business,” said Herbert Parker, TriMas board chair. TriMas will focus on its high-margin packaging platform and specialty products group that serves consumer and industrial markets.
