Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and corrosion challenges in precision machinery. The 316 stainless steel material provides excellent resistance to corrosive agents, making it suitable for food processing, chemical, and marine applications. Its 190mm shoulder length and precise 16mm shoulder diameter ensure accurate positioning of moving parts like bearings and pulleys, reducing wear and maintenance downtime. The knurled socket head design enhances grip during installation, while the Class 5g6g metric thread with a 1.75mm pitch offers reliable fastening in high-vibration environments. Ideal for assembly jigs, conveyor systems, and robotic arms, this screw delivers consistent performance where dimensional stability and corrosion resistance are paramount.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 specifications, with threads conforming to Class 5g6g tolerance for precise fit. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing safety and environmental standards for industrial use.
