Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 18-8 stainless steel material provides excellent corrosion resistance, essential for machinery exposed to moisture or chemicals. Its precise shoulder with minimal diameter and length tolerances acts as a pivot or spacer, preventing component misalignment and reducing vibration-induced wear in assemblies like rotating shafts, linkages, and precision guides. The coarse thread (1.5mm pitch) and Class 6g thread fit ensure quick, secure fastening even in softer materials or where repeated adjustments are needed. Combined with a hex socket drive for high torque application, this screw delivers reliable performance in demanding settings such as automotive jigs, conveyor systems, and electronic enclosures, enhancing operational efficiency and reducing maintenance downtime.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M10 thread size, 1.5mm coarse pitch, and 16mm thread length. The shoulder features precise dimensions: 12mm diameter (tolerance: -0.025 to 0 mm) and 25mm length (tolerance: 0 to 0.05 mm), ensuring accurate fit. Threads conform to Class 6g fit for consistent engagement. The product is manufactured from 18-8 stainless steel with a hardness of Rockwell B55 and tensile strength of 70,000 psi. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free from hazardous substances and suitable for global industrial use.
