Professional Applications & Engineering Value
This M6 hex head screw delivers critical engineering solutions for industrial assembly challenges. The Class 8.8 steel construction provides exceptional shear and tensile strength for heavy-duty machinery, structural frameworks, and equipment manufacturing. Partial threading concentrates strength where needed while reducing material weight. The zinc-plated finish combats corrosion in manufacturing plants, outdoor installations, and high-humidity environments. With coarse metric threading and external hex drive, installers achieve rapid assembly without compromising joint security—ideal for production lines requiring both speed and reliability. These ISO 4014 compliant fasteners ensure dimensional consistency across global supply chains.
Specification Summary & Compliance
Manufactured to ISO 4014 specifications (equivalent to DIN 931) with Class 6h thread fit ensuring precise dimensional tolerances. The right-hand metric thread features M6x1mm coarse spacing with 18mm minimum threaded portion. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe industrial use. Mechanical properties include Rockwell C21 hardness and 110,000 psi tensile strength per Class 8.8 requirements.
