The Defense Logistics Agency (DLA) is conducting market research to identify companies capable of manufacturing a specific bolt (NSN 5306-015521655), currently sole-sourced to SPS Technologies, LLC. Interested parties must submit a response by Thursday, June 4, 2026, including company POCs and the manufacturer's location (city, state, or country). This is a Sources Sought Notice for informational purposes only, not a solicitation or request for proposals, and no funds are available to pay for response preparation. Companies seeking to become an approved source must submit a Source Approval Request (SAR) package demonstrating their product meets or exceeds the original equipment manufacturer's quality. The SAR package should be sent to the DLA Aviation SAR Program Office in Richmond, VA, unless an open solicitation exists, in which case it goes to the listed buyer.
