These are custom metric button socket screws we supply to our long time customer in 18-8 stainless steel material.  It is an M3 X 0.5 X 7.24MM button socket head cap screw with a 2MM hex socket drive at 1.04" minimum depth.  Production lead time is typically between 6 and 8 weeks, done domestically and supplied with material certs and certificate of conformance.  Our internal part number is 110319.

Large quantities of these custom made parts would be best supplied on a 12 month blanket purchase order basis.  The Blanket Order concept allows the customer to access the large quantity cost savings without paying upfront for the entire large quantity order. Instead we take on the burden of carrying the bulk inventory and only release the parts as needed, or often on a pre-scheduled basis provided by the customer.
