Value Collection KP66149 Hex Lock Nut 7/8-14 Grade C 20-pack

Product Description

The VALUE COLLECTION KP66149 is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loads. Manufactured from Grade C steel with a zinc-plated and waxed finish, this nut provides corrosion resistance and smooth thread engagement during installation. The 7/8-14 UNF thread size suits a wide range of mechanical and industrial assembly applications. Each package contains 20 nuts. Distorted-thread locking style creates interference fit without secondary locking elements, making it a dependable choice for high-vibration environments where re-torquing access is limited.

This hex lock nut is suited for mechanical assembly, industrial equipment, and structural fastening applications where a unified fine thread is specified. The right-hand thread direction follows standard convention. Typical install scenarios include securing shafts, flanges, and brackets in equipment that experiences continuous vibration or cyclical loading. The zinc and wax finish aids installation in dry or lightly oiled assemblies.
