- Enhanced durability and wear resistance from the black oxide finish, which also provides a sleek, non-reflective appearance.
- Precise alignment and smooth rotation ensured by the 140mm shoulder with tight diameter tolerance, reducing component wear.
- High mechanical strength with 70,000 psi tensile and 35,000 psi shear strength, suitable for demanding structural loads.
- Secure and efficient installation using the 8mm hex drive and knurled head, preventing tool slippage during high-torque applications.
- Reliable thread engagement with Class 5g6g fit and coarse M12x1.75mm thread, offering quick assembly and vibration resistance.
- Compliance with international standards including ISO 7379, RoHS 3, and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical challenges in precision assemblies, such as in machinery, automotive, and electronics. The 316 Stainless Steel material provides excellent resistance to corrosion and high temperatures, while the black oxide finish enhances surface durability and reduces galling. The 140mm shoulder length with minimal tolerance allows for exact positioning of moving parts, minimizing misalignment and extending component life. With a coarse thread and Class 5g6g fit, it ensures fast, secure fastening in high-vibration environments, making it ideal for pivots, guides, and rotating mechanisms where reliability is paramount.
Specification Summary & Compliance
This shoulder screw features a metric thread with M12x1.75mm coarse pitch and Class 5g6g thread fit for precise tolerance. The shoulder diameter is 16 mm with a tolerance of -0.072 to -0.01 mm, and shoulder length is 140 mm with 0 to 0.25 mm tolerance. It meets ISO 7379 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring adherence to environmental and safety regulations.
