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.
