Professional Applications & Engineering Value

This precision M6 shoulder screw delivers exceptional engineering value in demanding industrial applications where alignment accuracy and durability are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery operating in humid or chemically aggressive environments. The precisely machined 8mm shoulder diameter with tight tolerances ensures perfect component alignment in assemblies, eliminating play and reducing wear in rotating mechanisms. The socket head hex drive allows for high-torque installation in confined spaces, while the Class 6g thread fit with coarse pitch maintains secure fastening under vibration. Ideal for precision equipment, automation systems, and manufacturing fixtures, this metric shoulder screw solves alignment challenges while providing long-term reliability.

Specification Summary & Compliance

This shoulder screw features M6x1mm metric coarse threads with Class 6g thread fit for standard industrial applications. The shoulder maintains precise dimensions with 8mm diameter (-0.025 to 0 mm tolerance) and 18mm length (0 to 0.05 mm tolerance) for accurate component positioning. Manufactured to industry standards with RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, ensuring environmental responsibility and global regulatory acceptance.
