Professional Applications & Engineering Value
This M8 hex head screw is engineered to address critical challenges in industrial fastening, where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel material prevents rust and degradation in humid or chemical-exposed settings, extending service life and reducing maintenance costs. With a coarse thread pitch and Class 6g thread fit, it ensures secure engagement in metals, plastics, and composites, minimizing the risk of stripping or loosening under vibration. The partial threading design provides an unthreaded grip length for enhanced shear strength, making it ideal for machinery, construction, and automotive assemblies that require precise clamping force and durability.
Specification Summary & Compliance
This screw features a metric M8 x 1.25 mm coarse thread with Class 6g tolerance for consistent fit and performance. It is manufactured in accordance with DIN 931 specifications, ensuring dimensional accuracy for head width (13 mm), head height (5.3 mm), and length (140 mm). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in various industrial applications without hazardous substances.
