Professional Applications & Engineering Value
Engineered for demanding scenarios where standard right-hand threads are unsuitable, this M20 left-hand thin hex nut solves critical reverse-rotation challenges in machinery, automotive, and conveyor systems. The 18-8 stainless steel material provides excellent corrosion resistance, eliminating rust-induced failures in humid or chemical-exposed environments. Its fine metric thread pitch and Class 6H fit deliver vibration-resistant locking where precision torque control is essential. The thin DIN 439B profile accommodates space-constrained designs without compromising load distribution, making it ideal for equipment requiring reliable left-hand threaded fasteners that meet international standards.
Specification Summary & Compliance
This nut features a metric M20x1.5mm left-hand thread with Class 6H thread fit per ISO standards, ensuring precise tolerance. Manufactured to DIN 439B specifications with 30mm width and 10mm height for dimensional consistency. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety requirements for industrial components.
