NAICS 332722: Bolt, Nut, Screw, Rivet, and Washer Manufacturing

NAICS 332722 – Bolt, Nut, Screw, Rivet, and Washer Manufacturing covers the production of precision fasteners and hardware components critical to military, aerospace, and industrial applications. This sector manufactures standardized and custom-engineered fastening systems, including high-strength alloy bolts, locking nuts, structural rivets, and corrosion-resistant washers, often meeting stringent military specifications such as MIL-S-8835, NAS, AN, and SAE standards. These components are essential in the assembly of aircraft, armored vehicles, naval systems, and munitions, where reliability under extreme stress, vibration, and environmental conditions is non-negotiable. In government contracting, this NAICS supports supply chain resilience and defense industrial base sustainment, with demand driven by maintenance, repair, overhaul, and new platform production programs. Top contractors in this space include KI MACHINE TOOLS & PRODUCTIONS INC and EVERSTONE INDUSTRIES LLC, both specialized manufacturers with deep expertise in high-tolerance fastener production, alongside ALLOY SLING CHAINS, LLC, which provides load-bearing hardware for heavy equipment. Merrill Corporation and Caladwich Consulting LLC offer procurement and logistics support, while Aviation International Solutions, LLC bridges technical sourcing with defense supply chain compliance. The competitive landscape is dominated by small businesses and niche OEMs with AS9100 and ITAR certifications, competing on material integrity, traceability, and rapid response to military specifications. The Department of Defense is the dominant buyer, with procurement concentrated in the Army, Navy, and Air Force logistics and sustainment commands. Demand stems from fleet modernization, overseas contingency operations, and the repair of legacy platforms requiring certified replacement fasteners. Procurement often occurs through blanket purchase agreements and defense logistics agency contracts. The market is characterized by high barriers to entry due to material certification requirements and stringent quality control protocols, creating stable, long-term contracting relationships. Opportunities exist for certified small businesses capable of meeting military-grade tolerances and providing just-in-time delivery to forward-deployed maintenance depots.
