• Global compliance and safety meeting ISO 7379 standards, RoHS 3, and REACH, ensuring environmental and regulatory adherence for international projects.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 316 Stainless Steel material provides exceptional resistance to corrosion and oxidation, making it suitable for machinery in marine, chemical processing, and food-grade environments. The precision-machined 8mm shoulder diameter with minimal tolerance ensures exact positioning of components like gears, pulleys, and linkages, reducing misalignment and vibration. The knurled socket head with a 4mm hex drive allows for secure, high-torque installation, minimizing the risk of stripping and enhancing operator safety. With a coarse thread pitch and Class 5g6g fit, it supports rapid assembly in automated systems, while the robust 17mm shoulder length offers stable support for rotating parts, extending equipment lifespan and reducing maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 specifications, ensuring dimensional accuracy with a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. The metric thread follows Class 5g6g fit standards for consistent engagement. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting sustainable manufacturing practices.
