M12-1.75 x 55 18-8 Stainless Steel Metric Socket Head Cap Screw keeps the metric thread and length explicit for replacement work on stainless socket-head fastener locations. Use the listed metric pitch and length directly when replacing hardware from a European or Asian machine print. Metric drawings from European suppliers may call this broad austenitic stainless family A2; do not treat that as a strength-grade claim.

Outdoor production equipment and service panels may specify 18-8 metric fasteners for general weathering conditions.

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.
