Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial applications. Manufactured from 316 Stainless Steel, it offers excellent resistance to chemicals and moisture, making it perfect for machinery, automotive assemblies, and precision instruments. The coarse thread (M6x1mm) ensures quick and secure fastening, while the precise 70mm shoulder length acts as a reliable spacer or axle, maintaining exact positioning and reducing stress on threaded sections. The combination of a socket head with a knurled texture and a Black Oxide finish provides both mechanical grip and added corrosion protection, delivering long-term reliability and reducing maintenance needs in high-vibration or corrosive environments.

Specification Summary & Compliance

This metric shoulder screw features an M6x1mm coarse thread with a Class 5g6g thread fit for precision. The shoulder diameter is 8 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 70 mm with a tolerance of 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured to meet ISO 7379 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing safety and environmental responsibility.
