• High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength, ensuring reliable operation under heavy loads.
• Secure, non-slip fastening thanks to the knurled head and 8mm hex socket drive, allowing for high-torque installation without tool slippage.
• Accurate and reliable threading with Class 5g6g fit and coarse M12x1.75mm thread, facilitating quick assembly and vibration resistance.
• Global compliance and safety meeting ISO 7379, RoHS 3, and REACH standards, ensuring product quality and environmental responsibility.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical industrial challenges, such as misalignment and corrosion in precision assemblies. The 316 stainless steel material offers exceptional resistance to chemicals and saltwater, making it suitable for marine equipment, food processing machinery, and chemical handling systems. The black oxide finish not only enhances corrosion protection but also reduces friction during installation. With a 90mm shoulder length and precise diameter tolerance, it ensures accurate positioning of moving parts in robotics, conveyor systems, and automotive jigs, minimizing wear and extending service life. The coarse metric thread and hex socket drive enable efficient, high-torque fastening, reducing downtime in high-volume production environments.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, adhering to ISO 7379 manufacturing specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting sustainable procurement practices.
