Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial assemblies. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for machinery, automotive, and outdoor equipment exposed to moisture or chemicals. The hex socket head with knurling allows for high-torque installation without slippage, while the Class 5g6g metric thread with 1.75 mm coarse pitch ensures quick assembly and secure holding in metals and plastics. The precision-ground shoulder acts as a pivot, bearing, or spacer, maintaining exact component positioning under dynamic loads and reducing wear in rotating mechanisms.
Specification Summary & Compliance
The screw conforms to metric system standards with an M12x1.75 coarse thread and Class 5g6g thread fit per ISO tolerance guidelines. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is ±0.05 mm for precise engineering fits. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability.
