DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA AVIATION.DLA AV RICHMOND.DLA AVIATION · Response deadline: Fri, 23 Oct 2026
What the government is buying
The Defense Logistics Agency (DLA) Aviation is procuring nuts, self-locking, splin—mechanical fasteners used in aerospace applications. Self-locking nuts contain a design feature (such as a nylon insert, deformed threads, or a locking element) that resists loosening under vibration and torque cycles, making them critical for safety in aircraft and aviation systems. The "splin" designation refers to splined or spline-drive configuration, which allows for specific torque transmission and installation methods common in military aviation maintenance and assembly.
DLA Aviation serves as the primary supply chain manager for military aircraft parts, supporting all branches of the U.S. armed forces. As a Combined Synopsis/Solicitation, this notice both announces the requirement and invites offers simultaneously, streamlining the procurement process.

Who can bid
This opportunity is 100% set aside for small businesses under the Small Business Set Aside – Total program. To qualify, your business must meet the size standard for NAICS code 332722 (Bolt, Nut, Screw, Rivet, and Washer Manufacturing), which is typically 500 employees—verify the current standard at SBA.gov. You must also be registered in SAM.gov with active small business certifications, and your firm should be prepared to supply products meeting aviation-grade specifications (see the solicitation for exact technical requirements).
Given DLA Aviation's mission, prior experience with military specifications (MIL-SPEC), National Aerospace Standards (NAS), or aerospace quality systems (AS9100/ISO 9001) strengthens eligibility, though the specific requirements and any applicable QPLs (Qualified Products Lists) are detailed in the solicitation document.
How to put together a competitive bid
Understand the technical baseline. Self-locking aerospace nuts must meet precise material, torque, and environmental specifications. Review the solicitation for exact part numbers, thread sizes, materials (stainless steel, alloy steel, titanium), plating requirements, and applicable standards (e.g., MIL-DTL, NAS, or MS specifications).
Verify your supply chain and quality systems. DLA Aviation typically requires traceable manufacturing sources, lot control, and adherence to First Article Test (FAT) or qualification testing. Ensure your manufacturing process—or that of your approved subcontractors—can demonstrate compliance. If you lack manufacturing capability, consider teaming with a qualified manufacturer while maintaining your small business prime status.
Price strategically. Research DLA's historical pricing for comparable fasteners through tools like FPDS or contact DLA's Customer Interaction Center. Factor in packaging, barcoding (MIL-STD-129), and shipping to DLA depots.
Prepare submission elements. Combined Synopsis/Solicitations often require immediate offer submission. Have your SAM registration, technical response, pricing, and any required representations (FAR 52.212-3, small business representations) ready before the deadline.
