The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 25 units of the Locknut (NSN 5310-016338457) as part of a presolicitation notice. This procurement is based on Emerson Drawing 20307, and the government does not possess the drawings or data rights necessary for additional sources to manufacture this item, making it uneconomical to reverse engineer. The contract will be awarded to a single source under FAR 6.302-1, with proposals accepted within 45 days of the notice publication, and interested parties are encouraged to contact Rachel E. Snyder at (717) 605-7296 or via email at RACHEL.E.SNYDER@NAVY.MIL for further details.
