Abstract

A decorative and protective cap for mounting on a threaded stud to conceal and protect a locknut threadably mounted therein, the cap including a shell having a cylindrical portion for providing a close fit with the outer surface of the locknut, a hexagonal wrench-receiving portion on the shell, and a plastic insert retained within the shell. The plastic insert has a portion with depressions therein for receiving internal lugs of the shell to thereby permanently mount the insert within the shell. An annular longitudinally slotted portion of the insert has an internal thread for mating engagement with the thread of the stud.
