M5-0.8 x 70 18-8 Stainless Steel Metric Socket Head Cap Screw fits metric fastening positions where clean appearance and general corrosion resistance both matter. Head height in this socket head pattern corresponds to the nominal metric thread diameter, a useful check when reviewing counterbore clearance. Metric drawings from European suppliers may call this broad austenitic stainless family A2; do not treat that as a strength-grade claim.

Protected marine-adjacent deck equipment may use 18-8 only when the exposure and specification allow it.

Special left-hand thread requests can be discussed when a metric stainless socket screw must match unusual equipment. Since 1962, Cold Headers has helped industrial buyers sort socket fasteners by material, head style, and exact size. Review the metric thread, length, head diameter, head height, socket size, and key engagement before substituting another screw.
