Professional Applications & Engineering Value

This M12 shoulder screw is engineered to solve critical alignment and pivot challenges in industrial applications. The 316 Stainless Steel material provides excellent resistance to chemicals and moisture, preventing failure in corrosive settings like marine or chemical processing equipment. The precision-machined 140mm shoulder acts as a reliable axle or spacer, ensuring components like gears, pulleys, and linkages rotate or are positioned accurately without misalignment. The coarse metric thread (M12x1.75) and Class 5g6g thread fit allow for rapid, secure fastening, reducing assembly time while maintaining joint integrity. Combined with the knurled socket head for high-torque drive, this screw delivers robust performance in machinery, automation systems, and heavy-duty assemblies where precision and durability are paramount.
