Professional Applications & Engineering Value
This M10 hex head screw is engineered to address critical challenges in heavy-duty mechanical assemblies, structural frameworks, and industrial machinery. The Class 10.9 steel construction, combined with a Rockwell C32 hardness and 150,000 psi tensile strength, ensures exceptional resistance to vibration loosening, dynamic loads, and fatigue failure. The partially threaded design with coarse metric thread (M10x1.5) allows for secure clamping over a 26mm threaded section while maintaining shank strength. Its external hex drive facilitates efficient installation in confined spaces, making it ideal for construction, automotive, and manufacturing applications where reliability and compliance with DIN 931 are paramount.
Specification Summary & Compliance
This fastener features a Class 6g thread fit per ISO metric standards, ensuring precise thread engagement and interchangeability. Manufactured in accordance with DIN 931 specifications, it guarantees dimensional accuracy for head width (17mm), head height (6.4mm), and overall length (125mm). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial sectors.
