M3-0.5 x 110 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. The cylindrical socket head gives wrench access through the internal hex while keeping the head shape familiar for counterbored metric designs. This material is often selected for washdown, humidity, and outdoor equipment where 18-8 is appropriate for the exposure.

Maintenance teams working on imported pumps, drives, and guards can keep the original metric size while moving to stainless 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.

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.
