Professional Applications & Engineering Value
These M10 hex head screws deliver critical engineering solutions for industrial and construction applications where high-strength fastening is paramount. The Class 10.9 steel construction with Rockwell C32 hardness provides exceptional resistance to shear and tensile forces, making them ideal for structural steel connections, heavy machinery assembly, and infrastructure projects. The coarse thread (M10x1.5) design ensures rapid installation and superior performance in materials where fine threads might strip or fail. With partial threading, these fasteners concentrate strength where needed most while reducing weight and material usage. The external hex drive accommodates standard tools for efficient installation in confined spaces, delivering reliable performance in demanding environments from manufacturing plants to construction sites.
Specification Summary & Compliance
Manufactured to ISO 4014 DIN 931 specifications with Class 6g thread fit tolerance ensuring precise dimensional accuracy. These metric hex head screws feature M10x1.5 coarse threads with 26mm minimum thread length and 40mm overall length. The Class 10.9 strength rating guarantees consistent performance under extreme conditions. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for industrial fastener applications.
