Professional Applications & Engineering Value
This M12 shoulder screw delivers critical engineering solutions where precise component alignment and rotational stability are paramount. The 30mm precision shoulder acts as an accurate locating dowel in machinery, automotive assemblies, and robotic systems, eliminating misalignment issues that cause premature wear. Manufactured from alloy steel with Rockwell C32 hardness, it withstands high shear forces and vibrational stresses in dynamic applications. The black oxide finish provides a protective barrier against oxidation in humid or chemically aggressive environments, while the Class 6g thread fit ensures consistent clamping force distribution. These features make it ideal for precision equipment, manufacturing jigs, and conveyor systems where dimensional accuracy and long-term reliability are non-negotiable.
Specification Summary & Compliance
Manufactured to metric standards with M12x1.75 coarse threads and Class 6g thread fit tolerance. Shoulder diameter maintains -0.072 to -0.01 mm tolerance with shoulder length controlled within 0 to 0.25 mm variation. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence for industrial distribution.
