M3-0.5 x 90 18-8 Stainless Steel Metric Socket Head Cap Screw identifies the exact metric size for a stainless socket head cap screw used in machinery and equipment panels. Use the listed metric pitch and length directly when replacing hardware from a European or Asian machine print. For stainless-on-stainless assembly, run threads at moderate speed and use lubricant or anti-seize when galling is a concern.

Outdoor kiosks and enclosures can use 18-8 metric socket screws where weather exposure is present but 316 is not specified.

Cold Headers can help identify hard-to-find metric stainless sizes while preserving the required thread and length. Review the metric thread, length, head diameter, head height, socket size, and key engagement before substituting another screw.
