Professional Applications & Engineering Value
This M6 shoulder screw delivers critical engineering value in precision assembly applications where component alignment and corrosion resistance are paramount. The 18-8 stainless steel construction combined with the precisely machined 8mm shoulder diameter creates an ideal pivot point or locating feature in machinery, automotive, and electronic assemblies. The metric coarse thread with 1mm pitch provides rapid installation while maintaining secure fastening in plastic, aluminum, and steel components. The socket head design with hex drive enables high-torque installation in confined spaces, making these precision shoulder screws essential for jigs, fixtures, and rotating mechanisms requiring exact radial positioning and durability.
Specification Summary & Compliance
Manufactured to exacting metric standards with Class 6g thread fit tolerance and precise shoulder dimensions (8mm diameter with -0.025 to 0 mm tolerance, 10mm length with 0 to 0.05 mm tolerance). Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The right-hand thread with coarse spacing follows standard metric threading conventions for broad compatibility across industrial applications.
