Professional Applications & Engineering Value

This precision shoulder screw delivers critical engineering value in applications requiring exact component positioning and rotational control. The 18-8 stainless steel material with passivated finish provides excellent corrosion resistance, making it suitable for manufacturing equipment, automation systems, and precision instruments exposed to moisture or chemicals. The M6x1mm coarse thread with Class 6g tolerance ensures rapid assembly while maintaining secure fastening. The precisely machined 8mm shoulder diameter with tight tolerances acts as a pivot point or locating dowel, eliminating misalignment issues in rotating assemblies, machinery, and fixturing applications. The hex socket head with 4mm drive size allows for high-torque installation in space-constrained environments, reducing assembly time while providing reliable clamping force for demanding industrial applications.

Specification Summary & Compliance

This M6 shoulder screw features Class 6g thread fit per metric standards with precise shoulder diameter tolerance of -0.025 to 0 mm and shoulder length tolerance of 0 to 0.05 mm. The manufacturing process ensures consistent dimensional accuracy for reliable performance in precision assemblies. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest industry standards for restricted substances and chemical safety in industrial components.
