What the government is buying

The Navy is soliciting for nuts, plain, hexagon—a type of fastener hardware. This is a supply acquisition for the Naval Supply Systems Command (NAVSUP) Weapon Systems Support activity in Mechanicsburg, Pennsylvania. NAVSUP WSS serves as the Navy's primary provider of logistics and supply support for weapons systems, managing spare parts and maintenance material for naval aircraft, ships, and submarines.

Hexagon plain nuts are standard threaded fasteners used with bolts in mechanical assemblies. Given the classification code 5310 (Nuts and Washers) and NAICS code 332722 (Bolt, Nut, Screw, Rivet, and Washer Manufacturing), this procurement involves basic hardware items manufactured to military or industry specifications.

These components typically support repair, maintenance, and overhaul activities across Naval weapons platforms. The specific quantities, technical specifications (such as material grade, thread size, coating requirements, and applicable military standards), and delivery schedule are not specified in the available metadata—see the solicitation for complete requirements.

Key facts

Who can bid

This solicitation is fully open with no set-aside designation, meaning any responsible source may submit an offer regardless of business size or socioeconomic status. Nonetheless, NAICS 332722 carries a 500-employee small business size standard, so small businesses in fastener manufacturing are strongly positioned to compete.

Eligible bidders typically include:

• Manufacturers of industrial fasteners with capabilities in cold-heading, machining, or forging hex nuts to specification
• Distributors holding manufacturer authorizations and quality certifications (if permitted; see the solicitation for source approval requirements)
• Firms with demonstrated experience supplying to defense or aerospace channels

Standard SAM.gov registration, active CAGE code, and appropriate representations and certifications are required.

How to put together a competitive bid

Fastener procurements to NAVSUP WSS emphasize quality assurance, traceability, and delivery reliability over lowest price alone. Consider these factors:

Technical compliance: Review all referenced military specifications (potentially MIL-DTL-25027, MS or NAS standards, or industry equivalents such as ASME B18.2.2). Verify your manufacturing or sourcing chain can produce nuts meeting exact dimensional, material, and mechanical property requirements. First Article Testing or Source Inspection may apply—see the solicitation.

Quality system: NAVSUP WSS suppliers typically need evidence of a formal quality management system. ISO 9001 or AS9100 certification strengthens your proposal. Be prepared to submit material certifications, test reports, and lot traceability documentation.

Past performance: Document prior deliveries of similar fasteners to DOD or commercial aviation/military customers. On-time delivery metrics and quality acceptance rates matter.

Pricing strategy: Analyze raw material (steel, stainless steel, brass, or specialty alloys) cost volatility and build appropriate escalation protections. Clarify whether the solicitation contemplates single-award or multiple-award—see the solicitation.

Packaging and marking: Defense supply chains require strict MIL-STD-129 labeling and preservation methods. Noncompliant shipments risk rejection.
