Tantalum Bolt & Fastener, LLC

Tantalum Bolt & Fastener, LLC, doing business as Extreme Bolt & Fastener, manufactures specialized fasteners—bolts, nuts, screws, studs, rivets, and washers—for the U.S. Navy as a prime contractor, competing predominantly in full-and-open procurement and small business set-asides. The company is a small business based in Waltham, Massachusetts, operating under primary NAICS 332722 (Bolt, Nut, Screw, Rivet, and Washer Manufacturing) and competes across total small business set-aside and non-set-aside purchase orders.

Customer concentration is extreme. The top five funding agencies account for 98 percent of awards, with the Naval Sea Systems Command (NAVSEA) dominating both volume and dollars: 167 awards carrying $8.5 million in combined potential value. The U.S. Pacific Fleet Forces, Naval Air Systems Command, Naval Supply Systems Command, and the Office of Naval Research round out the active set with minimal volume. A single award from the Army's Redstone contracting command for $14,280 in hardware parts for Letterkenny Army Depot in July 2025 represents the only non-Navy prime work in the recent portfolio. NAVSEA's concentration reflects the company's role as a specialized supplier for naval shipbuilding, vessel maintenance, and fleet readiness—supporting programs including DDG-51 destroyer maintenance (USS Cole, USS Porter, USS Gonzalez), LPD amphibious ships (USS Green Bay), and submarine programs (Ohio Class TRID installations).

Tantalum Bolt & Fastener holds a single-award $5 million Blanket Purchase Agreement with NAVSEA awarded May 15, 2024, and running through June 14, 2029. This BPA serves as the master vehicle for the majority of the company's work; most recent purchase orders cite it as the underlying procurement authority. Representative prime work includes a $91,384.94 total small business set-aside for specialized fastening hardware in January 2026; a $75,635.20 total small business set-aside in June 2025 for threaded fasteners and shear pins fabricated from Inconel 718 for the Naval Foundry and Propeller Center; a $69,344 total small business set-aside in July 2024 for hex head screws, nuts, and washers meeting AMS-5669 specifications; and a $65,092.88 total small business set-aside in May 2025 for heavy hex nuts for USS Green Bay's Ship Service Diesel Generator replacement. The company manufactures components from advanced corrosion-resistant materials including Inconel, K-Monel, stainless steel, nickel alloys, and nickel-chromium-molybdenum compositions to meet stringent military specifications (MIL-DTL-1222, SAE AMS, ASTM standards).

Activity has grown substantially year over year, from 13 awards in 2022 to 52 in 2025, with 10 awards already logged through early 2026. The $8.6 million in combined potential value across 183 total awards (176 prime, 7 sub) reflects a business built on high-frequency, moderate-dollar purchase orders under the NAVSEA BPA rather than large single contracts. Only two awards face ultimate completion inside the next twenty-four months (combined potential value $59 thousand), leaving the vendor with minimal recompete cliff exposure.

Tantalum Bolt & Fastener serves as a subcontractor to General Dynamics Mission Systems on Littoral Combat Ship Independence Class life-cycle support, with multiple sub-awards spanning 2024 through 2025, and to General Atomics on CVN 81 and CVN 79 electromagnetic aircraft launch system (EMALS) pre-production and long lead-time material procurement in 2025. Across all subcontract work, the company delivers specialized fastening components in support of major platform programs.

The vendor's posture is predominantly small business set-aside at the point of award—approximately 60 percent of purchase orders carry total small business set-aside designations—though a substantial share (40 percent) compete full-and-open. No specific 8(a), HUBZone, SDVOSB, or WOSB certification appears in the source; the vendor qualifies as a small business under the 600-employee size standard for NAICS 332722 and competes consistently across both set-aside and unrestricted solicitations. Performance occurs primarily in Waltham, Massachusetts, with secondary sites including Kittery, Maine; Portsmouth, Virginia; Brownstown Township, Michigan; and Lincoln Acres, California when fulfilling specific regional naval shipyard delivery requirements.
