Professional Applications & Engineering Value
This M8 nylon insert locknut delivers critical vibration resistance where conventional nuts fail. The zinc-plated steel construction provides essential corrosion protection while the nylon insert creates consistent friction locking that prevents loosening under dynamic loads. Engineered with Class 6H precision threads, these locknuts ensure reliable engagement with mating metric coarse thread fasteners in machinery, automotive assemblies, and industrial equipment. The external hex drive allows for efficient installation using standard tools, while the 220°F temperature rating makes these nuts suitable for environments where thermal cycling occurs. Ideal for applications requiring repeated disassembly and reassembly without compromising locking performance.
Specification Summary & Compliance
This locknut features M8 x 1.25mm coarse metric threads with Class 6H thread fit tolerance per ISO standards. The 13mm width and 8mm height provide standardized dimensions for consistent application across industrial fastening systems. Manufactured from zinc-plated steel with right-hand thread direction and external hex drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial procurement.
