Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and pivot point challenges in precision machinery, automation systems, and assembly jigs. The 316 stainless steel material offers excellent resistance to chemicals and saltwater corrosion, making it suitable for food processing, marine, and pharmaceutical equipment. The black oxide finish not only enhances corrosion protection but also reduces galling during installation. The integrated 18mm shoulder acts as a precise locating dowel, minimizing part movement and bearing surface wear in rotating assemblies. With its hex socket drive and knurled head, it ensures secure handling and high torque transmission without slippage, streamlining maintenance and improving operational reliability in industrial applications.

Specification Summary & Compliance

This metric shoulder screw features an M6x1mm coarse thread with a Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy. The shoulder diameter is manufactured to a tight tolerance of -0.072 to -0.01 mm, and the shoulder length tolerance is controlled from 0 to 0.25 mm for consistent performance. It is produced in accordance with ISO 7379 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safety and sustainability in industrial components.
