• High-strength performance with 70,000 psi tensile strength and Rockwell B55 hardness, ensuring reliable fastening under heavy loads.
• Secure, high-torque installation using the 5mm hex socket drive, preventing cam-out and tool slippage during assembly.
• Enhanced grip and handling from the knurled head texture, allowing for easier manual adjustments in tight spaces.
• Reliable thread engagement with Class 5g6g metric coarse thread (M10x1.5), ensuring consistent fit and vibration resistance.
• Compliance with global standards including RoHS 3 and REACH, making it suitable for regulated industries and international supply chains.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to solve critical alignment and durability challenges in industrial applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, extending service life in machinery, automation systems, and outdoor equipment. The precision-machined shoulder with a diameter of 10 mm and length of 14 mm acts as a built-in spacer, ensuring accurate positioning of moving parts like gears, pulleys, and linkages—eliminating the need for additional bushings and reducing assembly complexity. Combined with the coarse thread pitch and hex socket head, it offers quick installation and high clamp load retention, making it a reliable choice for high-vibration environments and precision engineering projects.

Specification Summary & Compliance

This shoulder screw features a metric M10x1.5 coarse thread with a Class 5g6g thread fit for standard tolerance applications. The shoulder diameter tolerance is -0.04 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise dimensional control. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in electronics, automotive, and other regulated sectors without hazardous substances.
