M3-0.5 x 70 18-8 Stainless Steel Metric Flat Head Socket Cap Screw keeps the metric diameter, pitch, and overall length explicit for stainless countersunk fastening work. The flush surface helps reduce snag points around covers, guards, slide paths, and handled equipment faces.

Stainless enclosures and covers use countersunk metric hardware where a smooth outside surface improves handling and appearance. Some metric drawings call this 18-8 family A2 stainless; that is material wording, not a mechanical rating. 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. Cut-to-length service can be reviewed for non-standard metric lengths. 18-8 Metric Button Head Socket Cap Screws reduce projection without a countersink.
