We supplied 100 pieces of these 2.87" free length custom .250 wire compression springs to our aerospace customer with a first article inspection report (FAIR), MIL-STD-6866 dye penetrant inspection report (Type 1, Method A, Sensitivity Level 3), heat treat certs, and a certificate of conformance. The outside diameter is 1.218 +/- .010" and the inside diameter is .718". Heat treat was done to condition CH900 per MIL-H-6875. Production was done domestically with a rush option to help our customer get out of a timing jam.
