Professional Applications & Engineering Value
This precision shoulder screw delivers exceptional value in industrial applications requiring exact component positioning and corrosion resistance. The 316 Stainless Steel construction with passivated finish provides superior protection against chemical exposure and moisture, making it ideal for machinery, automotive assemblies, and marine equipment. The 10mm shoulder diameter with precise tolerance ensures perfect alignment in bearings, pulleys, and rotating mechanisms, eliminating play and reducing wear. The M8x1.25mm coarse thread with Class 6g fit enables rapid installation while maintaining vibration resistance. Engineered for heavy-duty shoulder screw applications, it combines dimensional accuracy with material durability to solve alignment challenges in precision assemblies.
Specification Summary & Compliance
This metric shoulder screw features M8x1.25mm coarse pitch threads with Class 6g thread fit per ISO standards. Shoulder diameter maintains -0.025 to 0mm tolerance with shoulder length tolerance of 0 to 0.05mm for precise assembly. Manufactured from 316 Stainless Steel with passivated finish, achieving Rockwell B79 hardness and 70,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety and industrial use.
