Professional Applications & Engineering Value

This M4 shoulder screw is engineered to solve critical alignment challenges in precision assemblies, such as in machinery, automotive, and electronic equipment. The 35mm shoulder length with controlled tolerances provides a stable bearing surface, preventing component misalignment and reducing wear. Made from 18-8 stainless steel, it resists corrosion in humid or chemical-exposed settings, while the hex socket drive and knurled head facilitate secure tightening in confined spaces. With a coarse thread pitch and Class 5g6g fit, it ensures quick assembly and reliable fastening, making it ideal for high-stress industrial applications where precision and durability are paramount.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 standards, with a shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm. Threads are metric M4 x 0.7mm coarse with Class 5g6g fit for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and regulatory acceptance in global markets.
