Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M8 hex head screws with Class 10.9 strength and coarse thread pitch deliver robust performance in machinery, automotive assemblies, and structural frameworks. The zinc yellow-chromate finish provides a protective barrier against oxidation and chemical exposure, addressing common corrosion issues in outdoor or humid environments. With a fully threaded metric design and precise Class 6h thread fit, these screws ensure uniform stress distribution and vibration resistance, reducing loosening in dynamic loads. Ideal for heavy-duty fastening where high tensile strength and durability are critical, they support efficient maintenance and long-term operational safety in B2B sectors.
Specification Summary & Compliance
This product meets ISO 4017 / DIN 933 specifications for dimensional accuracy, including M8 x 1.25mm coarse thread with Class 6h tolerance. It is manufactured from high-strength steel and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability for industrial use.
