Professional Applications & Engineering Value

This castle locknut with cotter pin security addresses critical safety concerns in vibration-prone industrial applications where fastener failure could lead to catastrophic results. The zinc-plated steel construction provides essential corrosion resistance while maintaining the high tensile strength required for heavy machinery, automotive, and construction equipment. The 3/4"-16 UNF fine thread configuration offers superior resistance to vibrational loosening compared to coarse threads, making it ideal for high-performance mechanical assemblies. The external hex drive allows for efficient installation with standard wrenches, while the castellated design accommodates cotter pins for positive mechanical locking that can be visually inspected for safety compliance.

Specification Summary & Compliance

This castle locknut features Class 2B thread fit per UNF standards with precise 3/4"-16 fine thread spacing and right-hand thread direction. The nut accommodates standard 5/32" cotter pins with minimum slot dimensions of 0.265" depth and 0.18" width. Manufactured from zinc-plated steel with standard hex profile and 1-1/8" width, this component is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations for industrial use.
