M5-0.8 x 50 18-8 Stainless Steel Metric Flat Head Socket Cap Screw matches metric equipment drawings that call for ISO 10642 flat head geometry, a 90° countersink, and stainless material. The internal hex drive keeps installation access from the top face, which is useful where side wrench clearance is limited.

Washdown machinery panels, access covers, and stainless guards use these screws where metric drawings call for a flush fastener. Flat head screws measure length overall, including the head, so this size is selected by the total screw length shown on the print. Confirm overall length, head diameter, head height, socket size, and key engagement before substitution.

Cold Headers has supported specialty socket fastener sourcing since 1962, including exact metric sizes for maintenance and production work. Compare 18-8 Metric Socket Head Cap Screws when a full cylindrical head is preferred.
