Professional Applications & Engineering Value
This precision shoulder screw delivers critical engineering value in applications requiring exact rotational alignment and axial positioning. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining 70,000 psi tensile strength for high-stress environments. The precisely machined 8mm shoulder diameter with tight tolerances ensures components maintain perfect alignment, eliminating play and reducing wear in rotating assemblies. The hex socket drive enables secure installation in confined spaces, while the Class 6g thread fit and coarse pitch provide reliable fastening that resists loosening under vibration. Ideal for precision machinery, automation equipment, and industrial fixtures where dimensional accuracy and durability are paramount.
Specification Summary & Compliance
This M6 shoulder screw features 1mm coarse pitch threading with Class 6g thread fit per metric standards. The precision shoulder maintains 8mm diameter with -0.025 to 0 mm tolerance and 5mm length with 0 to 0.05 mm tolerance for exact alignment applications. Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for industrial use.
