Professional Applications & Engineering Value

This M12 shoulder screw delivers critical engineering solutions where precise rotational or linear motion is required. The 316 stainless steel material resists pitting and corrosion in aggressive settings like chemical processing equipment, marine hardware, and food machinery. Its 50mm shoulder length with tight diameter tolerance acts as a reliable pivot or spacer, eliminating misalignment in assemblies such as conveyor systems, robotic arms, and precision instruments. The coarse metric thread (M12x1.75) and Class 5g6g fit ensure quick assembly and stable performance under vibration, while the socket head with knurling allows for high-torque installation without slippage. This design minimizes maintenance downtime and extends service life in industrial applications demanding repeatable accuracy.
