• Quick and Secure Installation – The 6 mm hex socket drive allows for easy, high-torque tightening with standard tools, speeding up assembly processes.
• Reliable Thread Engagement – Class 5g6g thread fit and coarse M10x1.5 thread offer consistent, secure fastening with reduced risk of cross-threading.
• Broad Industry Compliance – Meets ISO 7379 specifications and is RoHS 3 and REACH compliant, ensuring safe use in regulated sectors.
• Optimized for Heavy-Duty Use – Rockwell C32 hardness and robust construction deliver long service life in demanding mechanical applications.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and heavy equipment. The alloy steel construction and black oxide finish provide excellent resistance to corrosion and wear, extending component life in environments exposed to moisture, chemicals, or constant friction. The smooth shoulder with precise diameter and length tolerances ensures accurate alignment of moving parts—such as in bearings, pulleys, or linkages—reducing vibration and preventing premature wear. With a coarse metric thread (M10x1.5) and right-hand thread direction, it enables rapid assembly and disassembly while maintaining secure holding power. Ideal for use in industrial robots, conveyor systems, and automotive assemblies, this screw delivers reliable performance where high tensile strength and dimensional accuracy are paramount.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 standards, with thread fit classified as Class 5g6g for consistent dimensional accuracy. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise fit in mating components. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting use in environmentally conscious and regulated industries.
