M6-1.0 x 30 18-8 Stainless Steel Metric Flat Head Socket Cap Screw is a flush-mount metric socket fastener for panels, guides, covers, and machine details built around metric prints. Use the verified diameter, socket size, head diameter, and key engagement values when checking countersink and tool fit.

Instrumentation faceplates and control housings rely on flush screw heads to avoid raised hardware around labels or operators. Stainless-on-stainless threads can gall when driven fast and dry, so moderate installation speed with lubricant or anti-seize is common practice. 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.
