We supplied these custom low head socket cap screws in alloy steel material with black oxide finish. Two different lengths were required by our customer - 28MM and 33MM under the head. We used COTS version of this DIN7984 socket cap screw at 35MM as the base part, then cutting and chamfering the parts to the appropriate lengths. The last step was the black oxide process - we mixed both sizes together to minimize the per piece cost to our customer.
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.
