Professional Applications & Engineering Value
These M8 hex head screws deliver exceptional engineering value in industrial applications where vibration resistance and structural integrity are critical. The Class 10.9 steel construction provides reliable performance in heavy machinery, construction frameworks, and equipment assembly. The partially threaded design concentrates strength where needed most, while the coarse metric thread (1.25mm pitch) ensures rapid installation in various materials. With external hex drive compatibility, maintenance crews can quickly service equipment using standard tools. The 100mm length and right-hand thread configuration make these high-strength hex bolts ideal for structural connections requiring repeated disassembly and reassembly without performance degradation.
Specification Summary & Compliance
This metric hex bolt features precise M8 x 1.25mm threading with Class 6g thread fit tolerance according to ISO standards. Manufacturing complies with ISO 4014 DIN 931 specifications for dimensional accuracy and mechanical properties. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors. With 22mm minimum thread length and 100mm total length, these screws maintain consistent performance in applications requiring partial threading and standardized external hex drive compatibility.
