Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical alignment and corrosion challenges in demanding applications. The 316 Stainless Steel construction, combined with a Black Oxide finish, provides exceptional resistance to chemicals and moisture, making it suitable for marine, chemical processing, and outdoor equipment. The 25mm shoulder length with minimal tolerance ensures precise component spacing and rotational stability in assemblies like machinery linkages, bearing mounts, and precision instruments. The hex socket drive and knurled head facilitate easy installation in confined spaces, reducing assembly time while maintaining high tensile strength for secure fastening under dynamic loads.

Specification Summary & Compliance

This shoulder screw adheres to metric coarse thread standards with M10x1.5 thread size and Class 5g6g thread fit for consistent performance. Dimensions include a shoulder diameter of 12 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 25 mm (tolerance: 0 to 0.25 mm). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial use.
