ABSTRACT:
A locknut having a single-turn thread for securing electrical fittings, threaded conduit and the like to electrical junction boxes and the like is disclosed. The locknut comprises a generally cylindrical portion, a flange portion attached to the cylindrical portion, a plurality of teeth attached to and projecting radially outwardly of the flange portion and axially beyond the end of the flange portion, and a standard thread attached to and extending for substantially only a single turn interiorly of the cylindrical portion. The thread has an included angle corresponding to that of a standard thread, for example, 60.degree.. The teeth seat against a work surface when the locknut is threaded onto the fitting and act as springs which can compensate for a small degree of element loosening by spring recovery. In addition, the thread of the locknut is flexible so that both the teeth and thread act as springs working in conjunction with each other.
