Professional Applications & Engineering Value
This M20 nylon insert lock nut delivers critical vibration resistance in demanding industrial environments where loosening under dynamic loads poses significant safety risks. The zinc-plated steel construction provides essential corrosion protection while maintaining the Class 8 strength rating required for heavy machinery, automotive assemblies, and structural applications. The fine 1.5mm thread pitch ensures maximum thread engagement and superior clamping force distribution, while the nylon insert locking mechanism creates consistent friction that prevents back-off without damaging mating threads. Engineered to DIN 982 and ISO 7040 standards, this metric lock nut offers reliable performance in manufacturing equipment, transportation systems, and construction machinery where vibration-induced failure is not an option.
Specification Summary & Compliance
This M20x1.5mm lock nut features Class 6H thread fit tolerance with right-hand fine threads and standard hex profile measuring 30mm width and 22mm height. Manufactured to DIN 982 and ISO 7040 specifications with Class 8 strength rating and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The nylon insert maintains locking performance up to 220°F maximum temperature while the external hex drive ensures standard tool compatibility.
