Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and strength requirements in precision assemblies. The alloy steel construction, combined with a zinc-plated finish, offers superior corrosion resistance, making it ideal for machinery, automotive, and electronics where exposure to moisture or chemicals is a concern. The low-profile socket head and coarse thread pitch facilitate efficient installation in tight spaces, reducing assembly time while maintaining a secure fit. The precisely machined shoulder acts as a pivot or spacer, minimizing wear on connected components and ensuring accurate rotational movement. By adhering to DIN 923 standards, this screw delivers consistent performance in jigs, fixtures, and rotating mechanisms, enhancing overall equipment reliability and reducing maintenance costs.

Specification Summary & Compliance

This shoulder screw features a Class 6g thread fit per ISO metric standards, with a shoulder diameter tolerance of -0.036 mm to 0 mm and length tolerance of 0.07 mm to 0.15 mm for precise engineering applications. It complies with DIN 923 for dimensional accuracy, RoHS 3 (2015/863/EU) for restricted hazardous substances, and REACH (EC 1907/2006) for chemical safety, ensuring full regulatory adherence in industrial and export markets.
