• High-strength performance with 70,000 psi tensile strength and Rockwell B79 hardness, offering reliable load-bearing capacity.
• Easy installation and removal using the 6mm hex socket drive and knurled head, allowing for high-torque application without slippage.
• Accurate and secure fastening with Class 5g6g thread fit and M10x1.5 coarse thread, ensuring consistent engagement and vibration resistance.
• Compliance with global environmental standards including RoHS 3 and REACH, making it suitable for regulated industries and export markets.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address common challenges in precision assembly, such as component wobble and misalignment in rotating machinery. The 50mm shoulder length acts as a precise bearing surface or pivot point, reducing wear on connected parts in applications like conveyor systems, automotive jigs, and robotic arms. Made from 316 stainless steel, it resists corrosion from moisture, chemicals, and salt spray, extending service life in demanding environments like food processing or marine equipment. The black oxide finish enhances surface hardness and provides a low-friction coating, while the hex socket head and knurled texture allow for secure tool grip during high-torque installations. This combination of metric thread precision and robust material properties ensures reliable performance in industrial applications where durability and accuracy are critical.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per metric standards, ensuring precise thread engagement and interchangeability. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, providing high dimensional accuracy for consistent assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. Manufactured to meet general industrial metric specifications, it is suitable for applications requiring reliable mechanical properties and environmental safety.
