Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and rotational challenges in industrial applications such as machinery assemblies, automotive components, and precision instruments. The 18-8 stainless steel material offers excellent resistance to rust and oxidation, prolonging service life in humid or corrosive settings. Its metric coarse thread (M6x1mm) and Class 5g6g thread fit provide reliable fastening with minimal risk of cross-threading, while the hex socket drive allows for high-torque installation in confined areas. The precisely machined shoulder acts as a dependable pivot or spacer, reducing wear on moving parts and ensuring accurate positioning. This design is ideal for high-tensile environments where durability and consistent performance are paramount.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 standards, with a Class 5g6g thread fit for precise metric threading. Key dimensional tolerances include a shoulder diameter of 8 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 6 mm (tolerance: 0 to 0.25 mm). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in environmentally conscious industries.
