Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and heavy-duty equipment. The 18-8 stainless steel material combined with a black oxide finish provides excellent resistance to corrosion and wear, extending service life in moist or chemically exposed settings. The 30mm shoulder length with minimal tolerance allows for exact component positioning, minimizing misalignment and vibration in rotating assemblies. Featuring a Class 5g6g thread fit and coarse 1.75mm pitch, it ensures rapid installation and reliable load distribution, making it ideal for industrial applications such as conveyor systems, motor mounts, and robotic arms where durability and precision are paramount.
Specification Summary & Compliance
The screw adheres to metric standards with precise dimensions: shoulder diameter tolerance of -0.04 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. Thread specifications include M12 size, 1.75 mm pitch, and Class 5g6g fit for consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
