Tantalum Bolt & Fastener, LLC

Tantalum Bolt & Fastener, LLC, doing business as Extreme Bolt & Fastener, manufactures specialized fasteners and fastening hardware for the U.S. Navy as a prime contractor on small-business purchase orders and a single-award blanket purchase agreement. The company is a small, for-profit limited liability company headquartered in Waltham, Massachusetts, operating under NAICS 332722 (Bolt, Nut, Screw, Rivet, and Washer Manufacturing) and competing predominantly in Total Small Business set-asides; approximately 60% of recent prime awards carry small-business set-aside designations.

Tantalum Bolt & Fastener's capability portfolio centers on manufacturing high-performance corrosion-resistant fasteners engineered for extreme maritime environments and military specifications. The vendor produces socket head cap screws, hex head screws, self-locking nuts, welding studs, coupling bolts and nuts, continuous-thread studs, and washers from advanced materials including Inconel, stainless steel (A286, CRES 316), nickel alloys (Alloy 400, K-Monel, MP35N), and nickel-chromium-molybdenum-columbium alloys. Representative prime awards include a $122.3 million combined-value order for socket flat countersunk head cap screws and special socket head cap screws (April 2025), a $91.4 million order for specialized fastening hardware under the blanket purchase agreement (January 2026), and a $83.6 million order for socket head cap screws (June 2023), all from Naval Sea Systems Command. Orders span both Waltham, Massachusetts and subordinate performance locations including Portsmouth Naval Shipyard (Kittery, Maine), Pearl Harbor Naval Shipyard (Hawaii), Seabrook (New Hampshire), and Puget Sound Naval Shipyard (Bremerton, Washington).

Customer concentration is extreme and single-vendor dependent. Naval Sea Systems Command accounts for 173 awards (98% by count) and $8.6 million combined potential value out of $8.8 million total; the remaining customer agencies—U.S. Pacific Fleet Forces (8 awards, $49 thousand), Naval Supply Systems Command (3 awards, $52 thousand), Office of Naval Research (1 award, $35 thousand), and Army Contracting Command Redstone (1 award, $14 thousand)—represent marginal share. The vendor has not pursued or succeeded on work outside the Naval Enterprise.

Tantalum Bolt & Fastener's primary vehicle is a $5 million single-award Blanket Purchase Agreement with Naval Sea Systems Command, awarded May 15, 2024, running through June 14, 2029. All other work flows through individual purchase orders (firm fixed price) issued under that BPA or through standalone small-business set-aside solicitations. The vendor does not hold a seat on government-wide contract vehicles, GWACs, or multi-award IDIQs.

Recent activity shows steady growth: thirteen awards in 2022, thirty-three in 2023, thirty-three in 2024, and fifty-two in 2025, indicating accelerating engagement with NAVSEA. Eighteen awards have been placed in 2026 to date. Four awards with combined potential value of $108 thousand face completion and recompete within the next twenty-four months, creating near-term recompete risk tied primarily to the BPA and purchase-order refresh cycles.

Tantalum Bolt & Fastener serves as a subcontractor on General Dynamics Mission Systems' Littoral Combat Ship Independence Class engineering and life-cycle support contracts (awarded January 2024, April 2024, May 2025, August 2025) and on General Atomics' CVN 81 and CVN 79 Electromagnetic Aircraft Launch System (EMALS) pre-production and long-lead-time material orders (November 2025). Sub-work centers on fastener supply and specialized hardware for combat systems integration.

The vendor's federal footprint is narrowly specialized and highly dependent on NAVSEA small-business purchase-order volume. It holds no multi-award vehicles, maintains no active pursuit strategy outside Navy shipbuilding and maintenance, and faces concentration risk should NAVSEA sourcing consolidate or shift to full-and-open competition. Strength lies in its established qualification for MIL-SPEC fastener production and its BPA position as a streamlined procurement vehicle for Navy fleet maintenance.
