Professional Applications & Engineering Value
This 7/8"-14 UNF castle locknut delivers critical safety in applications where vibration-induced loosening poses significant risks. The zinc-plated steel construction provides essential corrosion resistance for outdoor equipment, agricultural machinery, and automotive systems exposed to harsh conditions. The fine UNF thread configuration offers superior load distribution compared to coarse threads, while the Class 2B thread fit ensures precise engagement with mating components. The castle design with specifically engineered slot dimensions (0.204" depth minimum, 0.18" width minimum) guarantees secure cotter pin retention, making this external hex locknut ideal for axle assemblies, steering mechanisms, and other critical joints where failure is not an option.
Specification Summary & Compliance
Manufactured to exacting standards with Class 2B thread fit precision and UNF fine thread specifications (7/8"-14). Dimensions include 1 5/16" width across flats and 3/4" height. Designed specifically for use with 5/32" diameter cotter pins with minimum slot dimensions of 0.204" depth and 0.18" width. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations for industrial applications worldwide.
