Custom Aerospace Socket Head Cap Screws - 8-32 X 4.25" In 18-8 Stainless Steel Material

We supplied 54 pieces of these custom aerospace socket head cap screws to our long time customer.  They were made in the USA using 18-8 stainless steel material (no DFARS requirement on these) with a broached 9/64" hex socket drive with min .077" engagement depth.  1" of the overall 4.25" length under the head was threaded at 8-32.  Due to the smaller quantity required the thread was cut rather than rolled.  Material certs and a certificate of conformance was provided but no FAIR was required for this specific part.
