M20-2.5 x 45 Cup Point 18-8 Stainless Steel Metric Socket Set Screw is a stainless option for metric collars, knobs, and couplings in corrosion-prone settings.

Protected marine-adjacent deck mechanisms may call for stainless metric set screws, with final material selection based on exposure. A headless stainless set screw driven deeply into a stainless collar is a common galling scenario, especially without thread lubricant. 18-8 trades hardness for corrosion resistance; where maximum bite in dry service governs, Cup Point Alloy Steel Metric Socket Set Screws should be compared. 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.
