M10-1.5 x 45 18-8 Stainless Steel Metric Flat Head Socket Cap Screw combines a 90° flat head, metric thread, and internal hex drive for low-projection stainless fastening. The flush surface helps reduce snag points around covers, guards, slide paths, and handled equipment faces.

Metric fixture plates and inspection tooling use flat heads when a workpiece must rest on or pass across the fastened surface. 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 keeps this 18-8 metric flat head family separated from inch-series and alloy rows so purchasers can keep the drawing callout intact. 18-8 Metric Button Head Socket Cap Screws reduce projection without a countersink.
