Professional Applications & Engineering Value
These M14 hex head screws are engineered to address critical challenges in industrial fastening, where vibration loosening and material fatigue are common concerns. The Class 8.8 steel construction and fine thread pitch work synergistically to maintain clamp load integrity in dynamic applications such as heavy machinery, automotive assemblies, and structural frameworks. The zinc plating provides a sacrificial layer that significantly reduces oxidation, making these metric hex screws ideal for both indoor and moderately corrosive environments. With full threading along the 20mm length, they offer maximum engagement in tapped holes or with nuts, ensuring uniform stress distribution and preventing joint failure. Their compliance with ISO 8676/DIN 961 standards means they integrate seamlessly into global supply chains, reducing downtime and replacement costs.
Specification Summary & Compliance
This hex head screw features M14x1.5mm fine threads with Class 6h thread fit tolerance, ensuring precise engagement. Manufactured to ISO 8676 and DIN 961 specifications, it meets dimensional and mechanical requirements for consistent performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety regulations for hazardous substances.
