Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear. Made from 316 Stainless Steel, it resists corrosion from chemicals, moisture, and salt, making it suitable for marine, chemical processing, and food machinery applications. The coarse 1.25mm pitch thread and Class 5g6g fit ensure quick, secure fastening with minimal risk of stripping, while the 10mm shoulder diameter and 9mm shoulder length provide stable pivoting and alignment in rotating assemblies like bearings, pulleys, and linkages. The hex socket drive facilitates easy installation in confined spaces, enhancing assembly speed and reducing downtime in production lines.
Specification Summary & Compliance
This shoulder screw features a metric M8 x 1.25mm coarse thread with Class 5g6g tolerance for precise fit. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring dimensional accuracy. It meets ISO 7379 manufacturing specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable industrial use.
