Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address common challenges in precision machinery and assembly, such as misalignment and component wear. The 70mm shoulder length acts as a precise pivot or spacer, ensuring accurate positioning of parts like gears, bearings, and linkages in automotive, robotics, and conveyor systems. Made from alloy steel with a black oxide finish, it provides superior corrosion resistance and a low-glare surface, ideal for harsh operational environments. The coarse metric thread (M6x1mm) and Class 5g6g thread fit facilitate quick, secure fastening, reducing assembly time while maintaining high tensile strength. Its socket head design allows for efficient torque application in confined spaces, making it a reliable choice for high-precision industrial applications where durability and compliance with international standards are critical.

Specification Summary & Compliance
