Professional Applications & Engineering Value

This M20 nylon insert lock nut delivers critical vibration resistance for demanding industrial applications where mechanical stability is paramount. Engineered with zinc-plated steel and Class 10 strength rating, this metric lock nut prevents loosening in machinery, automotive assemblies, and structural frameworks subjected to constant motion or impact. The fine metric threading with precise Class 6H fit ensures uniform load distribution while the nylon insert creates consistent friction against bolt threads, eliminating the need for secondary locking mechanisms. Particularly valuable in industrial applications requiring reliable fastening in confined spaces, this locknut maintains integrity across temperature variations while meeting international DIN 985 and ISO 10511 standards for quality assurance.

Specification Summary & Compliance

This locknut features M20x2mm fine metric threading with Class 6H thread fit per ISO standards, ensuring precise dimensional accuracy. Manufactured to DIN 985 and ISO 10511 specifications with 30mm hex width and 20mm height profile. The product demonstrates full compliance with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, confirming environmental safety and restricted substance adherence for industrial applications.
