Professional Applications & Engineering Value
This M20 hex head screw delivers critical engineering advantages in industrial settings where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition prevents rust and degradation in chemical processing, marine, and outdoor applications, while the coarse 2.5mm pitch metric threading ensures rapid assembly in structural steel connections, machinery frames, and heavy equipment. The partially threaded 190mm design provides unthreaded shank sections for shear load management, making it ideal for high tensile strength applications requiring precise clamping without thread distortion. With external hex drive compatibility, maintenance teams can achieve proper torque values efficiently, reducing installation time in industrial fastening systems.
Specification Summary & Compliance
This metric hex head screw features M20 x 2.5mm coarse threading with Class 6g thread fit tolerance for precise engagement. Manufacturing adheres to ISO 4014/DIN 931 standards for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across global industrial markets.
