About the company
Clarendon Specialty Fasteners, Inc., operating as Clarendon Specialty Fasteners Inc. Division, is a foreign-owned, small disadvantaged business based in Irvine, California that manufactures and supplies aerospace-grade specialty fasteners, nuts, bolts, screws, rivets, and hardware components to the Department of Defense as a prime contractor (95% of recent awards) and as a subcontractor on defense aerospace programs. The company is a wholly owned division of Diploma Holdings, Inc., a for-profit parent entity headquartered in Clearwater, Florida. Clarendon competes exclusively in full-and-open procurements with no set-aside designations across its prime footprint.
Clarendon's federal business is almost entirely concentrated with the Defense Logistics Agency. The Defense Logistics Agency Aviation accounts for 113 awards with $313 thousand combined potential value, representing 76% of all prime awards, and the Defense Logistics Agency Troop Support Hardware accounts for 26 awards with $51 thousand combined potential value. The remaining customer base includes the Department of the Army, the National Aeronautics and Space Administration Glenn Research Center, and the Department of Homeland Security U.S. Coast Guard. The vendor's NAICS portfolio centers on bolt, nut, screw, rivet, and washer manufacturing (82 awards) and hardware manufacturing (48 awards), with PSC concentration in nuts and washers (37 awards), rivets (31 awards), screws (29 awards), and fastening devices (24 awards). Representative prime work includes a $28,174 DLA Aviation purchase order for self-locking nuts awarded July 26, 2024; a $16,574 firm fixed-price purchase order for close-tolerance screws awarded April 5, 2022; and a $14,695 DLA Aviation purchase order for self-locking nuts awarded February 16, 2022. The company also holds a position on an Army Indefinite Delivery Contract (W31P4Q25D0003) with two task orders.
In its subcontractor role, Clarendon supplies aerospace-qualified fasteners and fittings to Bell Textron on the Future Vertical Lift (FVL) Fixed Wing High-Speed Rotorcraft program, a pre-Major Defense Acquisition Program effort to develop next-generation tactical assault and utility aircraft for the Army, with sub-awards dating July through August 2025. The vendor also supplies fasteners to Dynetics, Inc. on defense production programs, with sub-awards in November 2025 and September 2026, and has provided fasteners to Sierra Space Corp for Tranche 2 Tracking Layer work as of June 2025.
Award activity peaked in 2023 with 55 awards but declined sharply to 4 awards in 2026 (as of September), reflecting either supply-chain maturation with consolidated orders or a recompete cliff. Over 149 total awards since 2012, Clarendon has obligated $911 thousand against a stated combined potential value of $394 thousand, indicating invoiced performance exceeding published ceiling values. All prime purchase orders carry firm fixed-price terms with performance conducted from the company's Long Beach, California facility. The vendor's federal footprint is characterized by high-volume, low-dollar-value transactional procurement of commodity fasteners to support military aircraft maintenance and defense industrial production.
