M5-0.8 x 35 Cup Point 18-8 Stainless Steel Metric Socket Set Screw is a stainless option for metric collars, knobs, and couplings in corrosion-prone settings.

Knobs and levers on wet-area controls use headless socket set screws to avoid an external wrenching head. A headless stainless set screw driven deeply into a stainless collar is a common galling scenario, especially without thread lubricant. The cup rim can leave a witness ring on the shaft; that localized bite is part of how the screw holds. 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.
