NAICS 339993: Fastener, Button, Needle, and Pin Manufacturing

NAICS 339993 – Fastener, Button, Needle, and Pin Manufacturing covers the precision production of mechanical fasteners, surgical pins, sewing buttons, and specialized needles used across defense, medical, aerospace, and industrial applications. This sector includes the fabrication of threaded and non-threaded fastening components such as rivets, clips, retainers, and micro-pins, often manufactured from high-strength alloys, stainless steel, titanium, or biomedical-grade materials to meet stringent military and regulatory specifications. These components are critical in assembly systems for aircraft, munitions, medical implants, and electronic enclosures, where reliability under extreme stress, corrosion resistance, and dimensional accuracy are non-negotiable. In government contracting, this NAICS supports supply chain resilience by providing essential subcomponents that enable larger systems, often sourced through indirect procurement channels or as part of broader assembly contracts. No contractor data is available to identify leading firms in this NAICS code within the federal marketplace. However, participants typically include small businesses with specialized machining capabilities, niche manufacturers certified to AS9100 or ISO 13485 standards, and subcontractors supplying to larger defense and medical device primes. No agency data is available to identify primary buyers. Demand is likely driven by the Department of Defense for munitions and avionics assembly, the Department of Veterans Affairs for orthopedic implants, and the National Institutes of Health for surgical instrumentation, though procurement is often embedded within broader systems contracts rather than stand-alone solicitations. The competitive landscape is fragmented, with low barrier-to-entry for small-scale production but high technical barriers for certification and quality control. Opportunities exist for manufacturers with certified processes, rapid prototyping capabilities, and experience in low-volume, high-precision runs. Growing emphasis on domestic sourcing and supply chain diversification may increase demand for U.S.-based producers with traceable manufacturing histories.
