Professional Applications & Engineering Value

This M10 shoulder screw with 1.5mm coarse pitch thread delivers exceptional engineering value in precision assembly applications. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining Rockwell B55 hardness for durability in mechanical systems. The 12mm shoulder diameter with controlled tolerances ensures precise rotational alignment in machinery, bearings, and pivoting mechanisms, eliminating the need for additional bushings. The hex socket drive enables high-torque installation in confined spaces, while the 60mm shoulder length provides consistent spacing in assemblies. These precision shoulder bolts are engineered to solve alignment and wear problems in automation equipment, conveyor systems, and precision instruments where dimensional stability and corrosion resistance are critical.

Specification Summary & Compliance

This metric shoulder screw features Class 5g6g thread fit per ISO standards with M10x1.5 coarse thread specification. The shoulder diameter maintains -0.072 to -0.01 mm tolerance while shoulder length carries 0 to 0.25 mm tolerance for precision applications. Manufactured from 18-8 stainless steel with 70,000 psi tensile strength and 35,000 psi minimum shear strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
