M4-0.7 x 8 18-8 Stainless Steel Metric Socket Head Cap Screw is used where metric socket screws need a corrosion-resistant stainless material in general service. The cylindrical socket head gives wrench access through the internal hex while keeping the head shape familiar for counterbored metric designs. Metric drawings from European suppliers may call this broad austenitic stainless family A2; do not treat that as a strength-grade claim.
Water and wastewater systems use this family in equipment housings, skids, and controls that see ordinary moisture. For stainless-on-stainless threads, moderate installation speed and a suitable lubricant or anti-seize help reduce galling risk.
Cold Headers has supplied specialty socket fasteners since 1962 and supports exact metric size identification. Review the metric thread, length, head diameter, head height, socket size, and key engagement before substituting another screw.
