• Reliable thread performance due to Class 5g6g thread fit and coarse M12x1.75 thread pitch, ensuring easy assembly and vibration resistance.
• Compliance with international standards including ISO 7379, RoHS 3, and REACH, guaranteeing safety and regulatory adherence.
• Durable and wear-resistant with Rockwell B83 hardness, maintaining integrity under repetitive loads and extended use.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address common industrial challenges such as component misalignment, corrosion-induced failure, and assembly inefficiency. Made from 18-8 Stainless Steel, it provides excellent resistance to rust and chemicals, making it suitable for machinery, automotive, and electronics sectors where environmental factors are a concern. The precision shoulder (16mm diameter, 10mm length) ensures accurate part location and reduces stress on threaded sections, while the hex socket drive and coarse thread pitch facilitate quick, secure fastening in high-vibration settings. By integrating ISO 7379 standards and robust material properties, this screw enhances equipment longevity and minimizes maintenance downtime in industrial applications.

Specification Summary & Compliance

The screw features a Class 5g6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, supporting precise engineering requirements. It complies with ISO 7379 for dimensional and mechanical specifications, RoHS 3 (2015/863/EU) for restricted substance control, and REACH (EC 1907/2006) for chemical safety, affirming its suitability for global industrial and commercial use.
