DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSUP.NAVSUP WEAPON SYSTEMS SUPPORT.NAVSUP WSS MECHANICSBURG.NAVSUP WEAPON SYSTEMS SUPPORT MECH · Response deadline: Mon, 30 Nov 2026
What the government is buying
The Department of the Navy, through NAVSUP Weapon Systems Support Mechanicsburg, is soliciting offers for self-locking nuts. These fasteners are classified under Federal Supply Class 5310, which covers nuts and washers. Self-locking nuts incorporate a locking feature—typically a nylon insert, deformed threads, or a captive washer—that resists loosening under vibration or torque reversal. They're standard hardware in military and aerospace applications where fastener security is critical.
This is a parts procurement for the defense supply system. NAVSUP Weapon Systems Support manages logistics for Navy and Marine Corps weapons platforms, so these nuts likely support aircraft, ship, or weapons system maintenance and production pipelines.

Who can bid
This solicitation is open to all responsible sources—no small business set-aside applies based on the available metadata. Any manufacturer or distributor registered in the System for Award Management (SAM) with the appropriate NAICS code may bid.
NAICS 332722 corresponds to "Bolt, Nut, Screw, Rivet, and Washer Manufacturing." Your firm should have this NAICS in your SAM profile. If you're a small business under this NAICS size standard, you may still compete, but you'll face unrestricted competition from large manufacturers and distributors.
Key eligibility requirements: active SAM registration, demonstrated manufacturing or supply capability for aerospace-grade or military-specification fasteners, and compliance with Defense Federal Acquisition Regulation Supplement (DFARS) sourcing requirements. See the solicitation for any specific quality certifications (AS9100, ISO 9001) or past performance requirements.
How to put together a competitive bid
For an unrestricted hardware solicitation at NAVSUP WSS, price and delivery typically dominate source selection. Consider these specifics:
Technical compliance: Self-locking nuts under FSC 5310 must meet precise military or aerospace specifications. Identify the exact spec (MS, NAS, or MIL-STD) referenced in the solicitation and confirm your product matches. Document your conformance through material certifications, test reports, and lot traceability records.
Pricing strategy: NAVSUP WSS routinely awards based on lowest price, technically acceptable (LPTA) criteria for standard hardware. Research historical prices through FPDS or GSA Advantage. Account for DFARS 252.225-7000 (Buy American) and specialty metal restrictions that may affect material sourcing costs.
Delivery performance: Evaluate your supply chain for raw materials and heat treatment capacity. NAVSUP WSS tracks delivery performance rigorously; propose realistic lead times you can meet. Consider offering alternate delivery schedules if the solicitation permits.
Past performance: Prepare relevant references from DLA, other NAVSUP activities, or aerospace OEMs for similar fastener contracts. See the solicitation for the specific past performance questionnaire format.
Packaging and marking: Defense logistics requires strict MIL-STD-129 or MIL-STD-2073 packaging. Factor these costs into your price.
