Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address common industrial challenges, such as misalignment and component wear in machinery. The alloy steel core, combined with a zinc-plated finish, offers robust corrosion resistance, making it ideal for automotive assemblies, conveyor systems, and precision equipment where exposure to moisture or chemicals occurs. The low profile socket head and coarse metric thread facilitate rapid installation in tight spaces, while the shoulder diameter of 8mm provides stable alignment for rotating parts like bearings or pulleys. By minimizing vibration-induced loosening and ensuring consistent thread fit, it reduces maintenance downtime and enhances operational reliability in industrial fastening applications.

Specification Summary & Compliance

This shoulder screw adheres to DIN 923 specifications, with precise dimensions including a thread size of M6x1mm and Class 6g thread fit for metric standards. The shoulder diameter tolerance is -0.036 mm to 0 mm, and shoulder length tolerance ranges from 0.07 mm to 0.15 mm, ensuring high accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and suitability for global industrial use.
