M8-1.25 x 100 18-8 Stainless Steel Metric Socket Head Cap Screw is an 18-8 stainless steel metric socket head cap screw for equipment built around metric drawings. Metric exactness matters here: an M8-1.25 x 30 requirement should remain metric, not a converted inch approximation. For stainless-on-stainless assembly, run threads at moderate speed and use lubricant or anti-seize when galling is a concern.

Conveyor frames in wet plants can use stainless metric SHCS sizes for covers, rails, brackets, and service panels. On many metric drawings, A2 stainless identifies the same broad chromium-nickel stainless family commonly called 18-8 in North America. For chloride-heavy or marine-adjacent service outside 18-8's usual range, Cold Headers can quote a 316 stainless metric request.

Cold Headers supports distributors, OEM buyers, and MRO teams that need uncommon metric socket screw lengths. Review thread, length, head dimensions, socket size, and key engagement before substitution.
