Professional Applications & Engineering Value

This M12 shoulder screw delivers critical engineering solutions where precise rotational and axial positioning is required. Manufactured from high-strength alloy steel with black oxide finish, it effectively resists corrosion in industrial settings while maintaining dimensional stability. The 25mm shoulder length with tight diameter tolerance provides accurate bearing surfaces for moving parts in machinery, eliminating misalignment issues. The Class 6g thread fit and coarse 1.75mm pitch ensure rapid assembly in production environments while the hex socket drive with knurled head prevents tool slippage during high-torque applications. Ideal for precision equipment, automation systems, and mechanical assemblies requiring reliable shoulder bolt performance.

Specification Summary & Compliance

This metric shoulder screw features Class 6g thread fit per ISO standards with shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for global industrial applications.
