Metric Blue UST194872 M12x1.75 Button Cap Screw 20mm

Product Description

The METRIC BLUE UST194872 is an M12x1.75 button socket cap screw designed for metric fastening applications requiring high strength and a low-profile head. Manufactured from Grade 12.9 alloy steel with a blue phosphate finish, this screw delivers exceptional tensile strength and corrosion resistance in demanding environments. The button head profile reduces surface stress and provides a clean finished appearance. At 20mm length under head and fully threaded, it is driven with an 8mm hex socket. It is installed by mechanical contractors, maintenance technicians, and equipment assemblers working with metric-threaded assemblies.

This screw is suited for use in equipment assembly, machinery maintenance, and structural fastening applications where a low-profile metric fastener is required. The fully threaded shank provides maximum thread engagement across the clamped joint. The blue phosphate finish offers mild corrosion protection appropriate for indoor and sheltered environments. It conforms to ISO 7380 fastener standards and is ordered in minimum quantities of 5 units, with individual package quantity of 1.

Compatibility

Designed as an ISO 7380-compliant metric fastener for use in M12x1.75 threaded applications across industrial equipment, machinery, and structural assemblies requiring a Grade 12.9 button socket cap screw.

Installation Notes

Installation is performed using an 8mm hex socket or Allen key driver. Follow the equipment manufacturer torque specifications for Grade 12.9 M12 fasteners and ensure mating threads are clean and free of debris before installation. Always confirm thread pitch compatibility before engaging the fastener. Blue phosphate finish is suited for sheltered environments; evaluate additional corrosion protection if the application involves outdoor or high-moisture exposure.
