Professional Applications & Engineering Value

This M20 left-hand threaded rod addresses critical engineering challenges in industrial settings where standard right-hand threads would compromise safety and performance. The steel construction with coarse 2.5mm pitch threading provides superior resistance to vibrational loosening in heavy machinery, conveyor systems, and rotating equipment. The fully threaded design along the entire 300mm length allows for unlimited positioning of nuts and components, making it ideal for adjustable structural frameworks, machinery mounting, and precision alignment applications. Its left-hand thread direction is particularly valuable in applications involving counter-rotating components, preventing unintended disassembly in critical systems. The combination of high tensile strength and Rockwell B49 hardness ensures long-term reliability in demanding environments where mechanical stress and wear resistance are paramount concerns.

Specification Summary & Compliance

This metric threaded rod maintains Class 6g thread tolerance as per ISO metric standards, ensuring precise fit with compatible nuts. Manufactured in compliance with DIN 976 specifications for dimensional accuracy and thread profile. The product meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations regarding chemical safety. With M20 x 2.5mm coarse thread spacing and left-hand thread direction, this fully threaded rod delivers consistent performance across industrial applications requiring reverse-thread security and high mechanical strength.
