Hub locknut

摘要

An electrical connector is secured to the wall of an electrical enclosure. The connector includes a hub which permits passage of electrical conductors in a conduit into the enclosure. The hub includes an elongate body having a conduit receiving end and a conductor egressing end which extends through the wall of the enclosure. A hub locknut is attachable to the conductor egressing end of the hub on the opposite side of the wall to secure the hub to the wall. The locknut includes circumferentially spaced raised flat surface portions adapted to be engaged by a tightening tool for rotatably tightening the locknut to the hub. The raised spaced surface portions define slots therebetween having tapered sidewalls which are adapted to be engaged by the blade of a screwdriver for rotatably tightening the locknut to the hub by impacting the screwdriver with a hammer.
