About the ISO 4762 Socket Head Cap Screw M5x8-A4
This ISO 4762 Socket Head Cap Screw is the M5 × 8 mm size in A4 stainless steel — the molybdenum-alloyed 316-type austenitic grade specified where chloride exposure, salt air or frequent washdown would corrode standard stainless. Per the ISO 4762 dimensional table for M5, the screw has an M5 × 0.8 coarse thread, a maximum head diameter of 8.5 mm, a 5.0 mm head height and a 4 mm hexagon socket. With only 8 mm of length under the head, it is a low-profile fixing for lids, keeper plates and shallow tapped bosses where thread depth is limited. The socket drive tightens from directly above, which is useful in counterbored or shielded locations where external-hex tooling cannot swing, and the recessed head leaves a clean, flush surface on finished equipment.
