These custom 316 stainless steel button head screws were manufactured domestically using ASTM A240 spec raw material. All dimensions and tolerances were to a drawing provided by our customer. M2.5 X .45 thread was incorporated (cut thread) with thread length set to 8MM. Head diameter was set to 4.50MM-4.7MM and head height at 1.36MM-1.50MM. Note that the button head was actually fully machined rather than the typical cold headed operation. The hex socket drive was broached as a result. Full certs were provided to our customer per request.
Large quantities of these custom made 316 stainless steel button head 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.
