Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and pivot point challenges in industrial applications. The 18-8 stainless steel material offers excellent resistance to oxidation and corrosion, extending service life in demanding settings like automation equipment, conveyor systems, and precision machinery. The 140mm shoulder length provides a precise unthreaded bearing surface, allowing rotating parts like gears, pulleys, and linkages to move freely without binding. The knurled socket head with an 8mm hex drive ensures a firm grip, reducing tool slippage during high-torque installations. Manufactured to ISO 7379 and featuring a Class 5g6g thread fit, this screw guarantees dimensional accuracy and reliable performance in high-stress assemblies.
