Professional Applications & Engineering Value

This M20 nylon insert lock nut delivers critical vibration resistance for machinery, automotive, and industrial equipment where loosening under dynamic loads poses significant safety risks. The 18-8 stainless steel construction provides exceptional corrosion resistance in demanding environments, while the nylon insert locking mechanism creates consistent friction against the bolt threads, maintaining clamp load without damaging mating surfaces. The coarse metric thread (M20x2.5mm) ensures rapid installation in production environments, and the external hex drive style accommodates standard tools for efficient maintenance. Engineered to DIN 982 standards, this lock nut offers reliable performance in applications from conveyor systems to structural assemblies where vibration-induced failure must be prevented.

Specification Summary & Compliance

This lock nut features M20x2.5mm coarse threads with Class 6H thread fit per ISO metric standards, ensuring precise dimensional accuracy and compatibility with corresponding bolts. Manufactured to DIN 982 specifications for nylon insert lock nuts, it maintains consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances above threshold limits. The nylon insert maintains locking effectiveness up to 220°F maximum operating temperature, while the 30mm width and 22mm height provide standard hex nut proportions for tool compatibility.
