Abstract
A lockable fastener connects together a plurality of components of a circuit breaker and maintains electrical conductivity between the components while permitting relative movement therebetween. The lockable fastener includes a first clinch nut member and a second clinch bolt member. The clinch nut member includes a threaded cavity formed therein, a side having opening therein, and a passageway between the side at the opening and a surface proximate the threaded cavity. The clinch bolt member includes a threaded shank. At least a portion of the threaded shank is threadably receivable in the threaded cavity of the clinch nut member, in order to axially align the clinch nut and clinch bolt members. The clinch nut and clinch bolt members are adapted to be locked by deformation of the surface of the clinch nut member to prevent loosening of the members.
