The Defense Logistics Agency Aviation – Richmond is conducting market research via a Sources Sought Notice to determine whether companies other than the approved sole sources can manufacture or legitimately obtain a close-tolerance bolt (NSN 5306-01-317-4318), currently supplied by Avibank Mfg. and Space-Lok. The solicitation identifier is being updated administratively due to the FY26-to-FY27 transition; historical documents remain valid and parties that already submitted capability packages need not resubmit. This notice is for information only, is not a solicitation or request for offers, and no funds are available to pay for response preparation. Qualified interested parties may submit capability responses and, if seeking Approved Source status, must apply through the Source Approval Request (SAR) program. For SAR submissions with no open solicitation, the address is DLA Weapons Support Richmond, Attn: DLA AVN-DU (SAR Program Manager), 6090 Strathmore Road, Richmond, VA 23237.
