Professional Applications & Engineering Value
This zinc-plated steel castle locknut delivers critical security in high-vibration applications where fastener failure is not an option. The cotter pin locking mechanism provides positive mechanical locking that surpasses friction-based alternatives, making it ideal for heavy machinery, automotive suspensions, agricultural equipment, and construction applications. The 1 1/2"-6 UNC coarse threads offer rapid assembly while maintaining strength, and the external hex drive ensures compatibility with standard industrial tools. The zinc plating creates a protective barrier against corrosion, extending service life in outdoor or chemically aggressive environments where ordinary fasteners would deteriorate prematurely.
Specification Summary & Compliance
This castle locknut features Class 2B thread fit per UNC standards with right-hand coarse threads (1 1/2"-6). Dimensions include 2 1/4" width and 1 5/16" height with a 5/16" cotter pin diameter requirement. The product is manufactured to industrial standards and complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring safe usage across various industrial sectors.
