- Environmental compliance assurance meeting RoHS 3 and REACH standards, enabling use in regulated industries worldwide
Professional Applications & Engineering Value
These M8 shoulder screws with TiCN coating provide critical solutions for precision machinery where alignment accuracy and durability are paramount. The 12mm shoulder length with precise diameter control acts as a reliable pivot or spacer in assemblies, eliminating misalignment issues in industrial automation equipment, conveyor systems, and robotic joints. Manufactured from 18-8 stainless steel, they resist chemical exposure and oxidation while maintaining 70,000 psi tensile strength under continuous operational stress. The Class 6g thread fit ensures vibration-resistant fastening in dynamic applications, making them ideal for high-precision engineering where component shift could cause system failure.
Specification Summary & Compliance
This metric shoulder screw features M8x1.25mm coarse threads with Class 6g thread fit per ISO standards, ensuring dimensional accuracy. The shoulder maintains precise tolerances (diameter: -0.025 to 0 mm, length: 0 to 0.05 mm) for consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material traceability.
