• Regulatory compliance with RoHS 3 and REACH standards for safe use in global industrial applications

Professional Applications & Engineering Value

This M6 shoulder screw delivers critical precision in applications requiring exact component positioning and rotational control. The 18-8 stainless steel material provides excellent corrosion resistance, eliminating failure risks in humid or chemically exposed settings. Its 8mm shoulder diameter with precise tolerance ensures accurate alignment in assemblies, reducing wear and misalignment issues. The hex socket head design permits high-torque tightening in limited-access areas, while the Class 6g coarse thread enables quick installation and maintains grip under dynamic loads. Ideal for machinery, automation systems, and precision instruments where dimensional accuracy and long-term durability are paramount.
