Professional Applications & Engineering Value
These M14 hex head screws are engineered to solve critical fastening challenges in demanding industrial settings. The Class 10.9 steel construction combined with 150,000 psi tensile strength makes them ideal for structural applications, machinery assembly, and heavy equipment where vibration resistance and joint integrity are paramount. The coarse metric thread with 2 mm pitch ensures rapid installation while maintaining secure fastening in steel frameworks, construction equipment, and industrial machinery. The partially threaded design provides concentrated clamping force where needed most, preventing joint loosening under dynamic loads. These industrial fasteners deliver consistent performance in manufacturing plants, automotive applications, and infrastructure projects requiring reliable, high-strength connections.
Specification Summary & Compliance
This M14 x 2 mm hex head screw features Class 6g thread fit tolerance and 50 mm length with 34 mm minimum thread length. Manufactured to ISO 4014/DIN 931 standards with right-hand thread direction and external hex drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
