Professional Applications & Engineering Value

This M12 shoulder screw delivers critical engineering value in applications requiring precise rotational alignment and structural stability. The 16mm shoulder diameter with controlled tolerances acts as a precision locating dowel, eliminating play in machinery assemblies while providing a smooth bearing surface. Manufactured from alloy steel with black oxide finish, these metric shoulder screws withstand harsh operating conditions where corrosion resistance and 140,000 psi tensile strength are essential. The Class 5g6g thread fit ensures consistent engagement in threaded components, while the hex socket drive facilitates installation in space-constrained industrial equipment. Ideal for precision machinery, automotive assemblies, and manufacturing jigs where dimensional accuracy and reliable performance are paramount.

Specification Summary & Compliance

This precision shoulder screw features M12x1.75 coarse metric thread with Class 5g6g tolerance and 18mm thread length. The shoulder maintains 16mm diameter with -0.072 to -0.01 mm tolerance and 16mm length with 0 to 0.25 mm tolerance. Manufactured to ISO 7379 specifications with Rockwell C32 hardness, this component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards for industrial use.
