Abstract
An improved lockable fastener that can be employed in a circuit breaker application includes a first member and a second member that are threadably cooperable with one another and a locking member that extends between the first and second members to resist loosening of the first and second members. The second member includes a threaded shank that is threadably received in a first threaded portion of a cavity formed in the first member. The locking member includes a threaded body and a taper, with the threaded body being threadably receivable in a second threaded portion of the first member, and with the taper being at least partially receivable in a receptacle formed in the shank of the second member. The receptacle defines a seat on the shank, and the taper engages the seat to deform at least a portion of the shank into engagement with a ledge that is interposed between the first and second threaded portions of the cavity.
