Abstract
A capped nut including a metal nut body, first threads on the outside of the metal nut body, a cap including a metallic shell and a non-metallic insert, dimples in the shell, a shoulder on the insert in contiguous relationship to the dimples for preventing the insert from being removed from the shell, second threads on the insert for mounting on the first threads of the metal nut body, and a rachet arrangement between the insert and the dimples for permitting the shell to override the insert when a turning force is applied to the shell which tends to overtighten the second threads on the insert with the first threads on the nut body but which provides positive engagement between the shell and the insert when a force is applied to the shell for unthreading the cap from the nut body.
