Professional Applications & Engineering Value

This M5 shoulder screw delivers critical engineering value in precision applications where component alignment and rotational stability are paramount. The alloy steel core, hardened to Rockwell C32, maintains dimensional stability under mechanical stress, while the black oxide finish resists corrosion in industrial atmospheres. The integrated 8mm shoulder length with controlled tolerances acts as a precise locating dowel, eliminating misalignment in assemblies and reducing wear on mating components. The hex socket head design enables high-torque installation without head stripping, making it ideal for automated assembly systems and maintenance operations in machinery, robotics, and precision equipment where class 5g6g thread consistency ensures reliable fastening performance.

Specification Summary & Compliance

Manufactured to precise metric dimensions including M5x0.8mm coarse thread with Class 5g6g thread fit, 6mm shoulder diameter (-0.072 to -0.01 mm tolerance), and 8mm shoulder length (0 to 0.25 mm tolerance). Compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as steel alloying element and REACH (EC 1907/2006) standards, ensuring environmental responsibility and global regulatory acceptance for industrial applications.
