M8-1.25 x 8 18-8 Stainless Steel Metric Socket Head Cap Screw pairs 18-8 stainless steel with standard metric socket head geometry for industrial assemblies. The internal hex drive supports compact installation where an external wrench would interfere with nearby components. For stainless-on-stainless assembly, run threads at moderate speed and use lubricant or anti-seize when galling is a concern.

Machine builders using metric prints rely on exact diameter, pitch, and length to maintain part interchangeability.

Special left-hand thread requests can be discussed when a metric stainless socket screw must match unusual equipment. Cold Headers supports distributors, OEM buyers, and MRO teams that need uncommon metric socket screw lengths. Review the metric thread, length, head diameter, head height, socket size, and key engagement before substituting another screw.
