Professional Applications & Engineering Value
This Grade 9 steel locknut with distorted thread top lock technology addresses critical vibration-induced loosening challenges in industrial settings. The engineered distortion in the upper threads creates consistent interference with mating bolts, maintaining clamp force where conventional nuts fail. The cadmium-plated steel construction provides essential corrosion resistance while the external hex drive ensures compatibility with standard wrenching tools. Ideal for heavy machinery, automotive assemblies, and construction equipment, this 1/4"-20 UNC locknut delivers reliable performance in applications subject to dynamic loads, thermal cycling, and continuous vibration. The coarse thread design facilitates quicker installation while maintaining superior locking capability in high-stress environments.
Specification Summary & Compliance
This locknut features 1/4"-20 UNC coarse threads with Class 2B thread fit for precision engagement, right-hand thread direction, and distorted thread top lock mechanism. Manufactured from Grade 9 steel with cadmium plating for corrosion protection. Dimensions include 7/16" width across flats and 19/64" height. Complies with relevant industrial standards for locknut performance and manufacturing specifications.
