ABSTRACT:
A tool bit for facilitating the application of a cigar lighter socket to an apertured mounting plate in an automobile, comprising a driving member having a shank receivable in the chuck of a power tool, and a separate shouldered plug member carried by the driving member and having a portion receivable in the mouth of the cigar lighter socket for the purpose of rotatably driving the same. Threads at the rear of the socket are screwed into mating threads of a clamping shell which is usually hand-held at the rear of the panel. The driving member and plug member can rotate with respect to one another against the action of a spring-charged clutch or detent on the members. When the plug member is inserted into the socket mouth it becomes keyed to the socket and effects a rotation of the same as power is applied to the driving member. When the desired torque is reached, the clutch slips, thereby insuring against overtightening and possible damage to the parts. The shoulder on the plug member prevents it from contacting the bimetal fingers which are deep in the socket, thereby eliminating inadvertent bending and malfunction of the same.
