Professional Applications & Engineering Value
This M12 shoulder screw delivers critical engineering solutions where precision alignment and rotational stability are paramount. The alloy steel core, hardened to Rockwell C32, withstands high cyclic loads in automation equipment, CNC fixtures, and conveyor systems. Its black oxide finish provides a protective layer against oxidation in humid or chemically exposed settings, while the knurled head enhances grip during manual adjustments. The 16mm shoulder diameter acts as a precise locating feature, eliminating bushing wear and reducing part misalignment in assembly jigs and robotic arms. With a coarse thread pitch and Class 5g6g thread fit, it maintains clamping force under vibration, making it ideal for heavy machinery and transportation equipment where reliability cannot be compromised.
Specification Summary & Compliance
This metric shoulder screw adheres to precise dimensional standards, including a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. The M12x1.75 coarse thread conforms to Class 5g6g thread fit specifications, ensuring compatibility with standard metric components. Manufacturing complies with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally regulated industries and international engineering projects.
