M10-1.5 x 55 18-8 Stainless Steel Metric Socket Head Cap Screw provides a direct metric-size option for repair work on imported equipment and stainless machinery. Metric exactness matters here: an M8-1.25 x 30 requirement should remain metric, not a converted inch approximation. Where maximum clamp strength matters more than stainless corrosion performance, compare Alloy Steel Metric Socket Head Cap Screws.

Water and wastewater systems use this family in equipment housings, skids, and controls that see ordinary moisture. On many metric drawings, A2 stainless identifies the same broad chromium-nickel stainless family commonly called 18-8 in North America.

The catalog keeps this 18-8 metric SHCS family separate from alloy and inch-series socket head cap screws. Review the metric thread, length, head diameter, head height, socket size, and key engagement before substituting another screw.
