Professional Applications & Engineering Value
This Class 10 heavy-duty nylon insert lock nut delivers exceptional engineering value in vibration-prone environments where fastener security is critical. The zinc-plated steel construction provides durable corrosion resistance while the nylon insert locking mechanism creates consistent friction against the mating bolt threads, preventing loosening from machinery vibrations, thermal cycling, and dynamic loads. Engineered with M18 x 2.5mm coarse metric threads and Class 6H thread fit, this external hex locknut ensures precise engagement and reliable performance in automotive assemblies, industrial equipment, construction machinery, and manufacturing systems where temperature fluctuations up to 220°F are encountered. The compliance with both DIN 985 and ISO 10511 standards guarantees international specification adherence for global supply chain requirements.
Specification Summary & Compliance
This locknut features M18 x 2.5mm coarse metric threads with Class 6H thread fit tolerance and right-hand thread direction. Manufactured from zinc-plated steel with standard hex profile (27mm width, 18.5mm height) and external hex drive style. The product conforms to DIN 985 and ISO 10511 specifications with Class 10 strength rating and meets RoHS 3 (2015/863/EU) compliance requirements for environmental regulations.
