M8-1.25 x 55 18-8 Stainless Steel Metric Socket Head Cap Screw is a stainless metric SHCS for applications that need compact internal hex access and a cylindrical head. ISO 4762 / DIN 912 geometry keeps the head diameter, head height, socket size, and key engagement tied to the metric diameter. 18-8 is a general-purpose stainless choice, so final material selection still depends on chemicals, chlorides, load, and service conditions.
Imported European machinery maintenance often requires exact metric socket screws to match the original bill of material. For stainless-on-stainless threads, moderate installation speed and a suitable lubricant or anti-seize help reduce galling risk. 18-8 inch-series Socket Head Cap Screws fit the same material preference when the print is not metric.
Cold Headers helps buyers keep material, metric pitch, length, and socket head geometry aligned with the print. Review the metric thread, length, head diameter, head height, socket size, and key engagement before substituting another screw.
