M3-0.5 x 4 Cup Point 18-8 Stainless Steel Metric Socket Set Screw gives metric shaft hardware a stainless cup-rim set screw for washdown service.

Metric collars, couplings, and guide rings use the cup rim to concentrate contact at the selected location on the shaft. Stainless-on-stainless threads can gall when driven fast and dry, so moderate installation speed and suitable lubricant help protect the tapped hole. Confirm the metric thread, length, cup diameter, and hex key before substituting another set screw.

Cold Headers helps maintenance teams and distributors match metric diameter, pitch, length, material, and point style.
