Professional Applications & Engineering Value

This M8 hex head screw delivers exceptional engineering value through its Class 8.8 steel construction and metric coarse threading, specifically designed to address industrial fastening challenges. The partially threaded configuration with 28mm minimum thread length provides optimal stress distribution while the external hex drive enables high-torque installation in confined spaces. Engineered to ISO 4014 standards, this 160mm fastener maintains precise dimensional stability under heavy loads, making it ideal for machinery assembly, structural frameworks, and equipment manufacturing where vibration resistance and long-term reliability are critical. The black surface treatment enhances corrosion protection in demanding environments while the right-hand coarse thread ensures rapid installation in production settings.

Specification Summary & Compliance

This metric hex head screw features M8 x 1.25 mm coarse threading with Class 6g thread fit tolerance and partial threading along its 160mm length. Manufactured to ISO 4014 specifications (equivalent to DIN 931) with dimensional accuracy including 13mm head width and 5.4mm head height. The fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for international industrial applications.
