Professional Applications & Engineering Value
Engineered for industrial machinery and structural assemblies, these M8 hex head screws deliver critical performance where vibration resistance and high tensile strength are paramount. The Class 8.8 steel construction with Rockwell C21 hardness prevents stripping and deformation under heavy loads, while the coarse metric thread (M8x1.25) ensures rapid installation and superior holding power in steel frameworks, equipment bases, and automotive components. The partially threaded design concentrates stress appropriately, reducing the risk of shear failure in dynamic loading conditions. With ISO 4014 compliance and external hex drive, these 150mm fasteners provide reliable, standardized solutions for maintenance teams and production lines requiring consistent, repeatable performance.
Specification Summary & Compliance
This metric hex head screw features precise Class 6g thread fit tolerances with M8x1.25 coarse threading and 28mm minimum thread length. Manufactured to ISO 4014 specifications (equivalent to DIN 931) with Class 8.8 strength grade certification. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors while maintaining 110,000 PSI tensile strength and dimensional accuracy for critical applications.
