Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and wear challenges in precision assemblies. The 316 Stainless Steel material offers excellent resistance to chemicals and saltwater corrosion, making it suitable for marine, food processing, and chemical industry equipment. The long, precisely machined 100mm shoulder acts as a sturdy axle or pivot point, preventing parts from shifting under load and reducing wear on mating components. The socket head with knurling and hex drive allows for secure tool engagement in confined spaces, while the Class 5g6g thread fit ensures reliable fastening in vibrating environments. This combination of features provides long-term reliability in linkages, rotating assemblies, and jigs, reducing maintenance needs and downtime.

Specification Summary & Compliance

This shoulder screw features an M6x1mm metric coarse thread with a Class 5g6g thread fit. The shoulder diameter is 8 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 100 mm with a tolerance of 0 to 0.25 mm. It is manufactured to meet ISO 7379 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
