These custom metric button socket cap screws are made using alloy steel material at 32-36 HRC with black oxide finish. The head diameter is 5.7MM and head height at 1.65MM, with a 2.0MM hex drive size. The overall length underneath the head is set at 6MM, of which 2.5MM is designed to be the un-threaded shoulder. Cold heading process was used to shape the head and the thread was rolled for optimal strength.
Large quantities of these custom made metric button socket head cap screws 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.
