Professional Applications & Engineering Value

This M8 hex head screw with black-oxide steel construction addresses critical industrial fastening challenges where corrosion resistance and structural integrity are paramount. The flange design eliminates the need for separate washers, distributing clamp load evenly to prevent surface indentation on softer materials. With its coarse 1.25mm pitch and Class 6g thread fit, it maintains secure connections in high-vibration environments common in machinery, automotive assemblies, and electrical enclosures. The combination of 130,000 psi tensile strength and Rockwell C27 hardness ensures reliable performance in heavy-duty applications, from equipment manufacturing to structural frameworks, while the fully threaded configuration provides consistent holding power across the entire fastener length.

Specification Summary & Compliance

This metric hex head screw features M8 x 1.25mm coarse threads with Class 6g thread fit per ISO standards, ensuring precise dimensional accuracy. The 12mm length and 18.2mm flange diameter maintain tight manufacturing tolerances for consistent performance. Manufactured from high-strength steel with black-oxide surface treatment, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial supply chains.
