What the government is buying

The U.S. Navy is soliciting offers for self-locking nuts through NAVSUP Weapon Systems Support in Mechanicsburg, Pennsylvania. This is a supply procurement for a hardware item classified under Federal Supply Classification (FSC) 5310, which covers nuts and washers. Self-locking nuts incorporate a locking feature—such as a nylon insert, deformed threads, or a locking mechanism—to resist loosening under vibration or torque, making them critical for military and aerospace applications where fastener security is essential.

NAICS 332722 refers to Bolt, Nut, Screw, Rivet, and Washer Manufacturing. Companies in this industry produce precision fasteners from various materials (steel, titanium, Inconel, aluminum) to military and commercial specifications. Given the Navy application, these nuts likely must meet military performance standards such as MIL-DTL- or NAS/MS specifications, requiring traceability, material certifications, and dimensional testing.

Key facts

Who can bid

This is a full and open competition with no small-business set-aside. Any responsible offeror—large or small—may submit a bid if they can:

• Manufacture or supply self-locking nuts to military specifications
• Demonstrate quality systems (typically ISO 9001 or AS9100 for aerospace/defense fasteners)
• Provide material certifications, test reports, and traceability documentation
• Meet any contract-specific qualification requirements (see the solicitation)
• Register in SAM.gov and hold an active CAGE code

Small manufacturers in NAICS 332722 should note they will compete directly with established defense contractors. The small-business size standard for this NAICS is 1,000 employees.

How to put together a competitive bid

For military fastener procurements, competitiveness depends on technical compliance, not just price. Specific steps:

Verify specification exactness. Self-locking nuts span dozens of MS/NAS/part-number variants with different sizes, materials, locking types, and temperature ratings. Confirm the exact National Stock Number (NSN) or part number and ensure your product matches every requirement—substitutions without pre-approval typically mean rejection.

Prepare quality documentation. Navy supply contracts require certificates of conformance, chemical/physical test reports, and lot traceability. If you lack in-house testing, budget for third-party laboratory validation.

Assess your supply chain. Raw material lead times for aerospace-grade alloys can extend months. Confirm you can deliver within any required schedule—see the solicitation for quantity and delivery requirements.

Review past performance weighting. NAVSUP solicitations often evaluate contractor performance history; document relevant deliveries to DLA, NAVSUP, or other defense customers.

Consider socioeconomic credits. Even without a set-aside, highlighting HUBZone, SDVOSB, or WOSB status may score favorably if the evaluation includes socioeconomic factors.

Price strategically. Fastener procurements are heavily price-competitive; understand your true manufacturing cost and any Buy American or Trade Agreements Act implications that affect sourcing.
