Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and fastening challenges in precision assemblies. The 18-8 stainless steel material offers excellent resistance to oxidation and corrosion, making it suitable for applications in machinery, automation, and outdoor equipment where environmental factors are a concern. The hex socket head with knurled texture provides a secure grip for high-torque installation, minimizing the risk of stripping and ensuring consistent clamping force. With a Class 5g6g thread fit and coarse 1.75 mm pitch, it facilitates quick assembly and reliable performance in dynamic load conditions, reducing maintenance needs and downtime in industrial fastening systems.
Specification Summary & Compliance
This shoulder screw adheres to metric system standards with a Class 5g6g thread fit for precise tolerance. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is -0.05 to 0.05 mm, ensuring accurate alignment. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally responsible industrial practices.
