M3-0.5 x 80 18-8 Stainless Steel Metric Socket Head Cap Screw supports maintenance work where corroded plain steel hardware is being replaced with 18-8 stainless steel. Head height in this socket head pattern corresponds to the nominal metric thread diameter, a useful check when reviewing counterbore clearance. 18-8 stainless steel is used for general corrosion resistance, clean appearance, and ordinary wet industrial service.

Common applications include food and beverage processing lines, guards, brackets, and washdown-adjacent machine panels.

Cut-to-length service can be reviewed for non-standard metric lengths when a catalog length does not match the drawing. Cold Headers supports hard-to-find metric stainless socket screw lengths while keeping the diameter, pitch, and length exact. Review the metric thread, length, head diameter, head height, socket size, and key engagement before substituting another screw.
