M3-0.5 x 80 18-8 Stainless Steel Metric Flat Head Socket Cap Screw supports compact stainless assemblies where top-side hex access is needed without a protruding cylindrical head. The head is intended to seat flush when the mating countersink is correctly prepared for the metric flat-head angle.

Conveyor wear strips and transfer plates can require flat heads so product or tooling passes over the surface without catching. 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 supports distributors and MRO buyers who need stainless metric socket products identified by exact size. 18-8 inch-series Flat Head Socket Cap Screws belong with inch drawings. 316 stainless metric flat heads are non-catalog quote requests for environments requiring that material.
