Professional Applications & Engineering Value
This M20 hex head screw delivers critical engineering solutions where structural integrity and corrosion resistance are paramount. The hot-dipped galvanized steel construction provides superior protection against rust and chemical exposure, making it ideal for construction, heavy machinery, and infrastructure projects exposed to weather elements. The Class 10.9 strength rating and 150,000 psi tensile strength ensure reliable performance in high-stress connections, while the partially threaded design with 97mm grip length prevents joint loosening under vibration. The coarse metric thread with 2.5mm pitch facilitates quicker installation in structural steel and industrial equipment, reducing assembly time while maintaining DIN 6914/ISO 7412 compliance for guaranteed dimensional accuracy.
Specification Summary & Compliance
This M20 hex head screw features precise Class 6g thread fit tolerance and 2.5mm coarse pitch threading according to metric standards. Manufacturing complies with DIN 6914/ISO 7412 specifications for dimensional consistency. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring compliance with international substance restrictions for industrial components.
