An electrical wiring box having a pair of factory-installed mounting elements associated therewith for permitting the quick and easy mounting of an electrical device within the wiring box. The wiring box includes bosses each having a generally-rectangular opening countersunk therein for receiving a corresponding mounting element. Each of the mounting elements includes a central portion having a screw-receiving opening and a pair of abutment edge portions adjacent to the opening, a pair of spaced-apart side portions integral with the central portion, and a pair of deflectible thread-engaging portions integral with the side portions and including pairs of retention wing portions at the terminations thereof. When inserted into their associated openings, the edge portions of the central portions of the mounting elements abut against shoulders adjacent to the openings, thereby limiting the forward entry of the mounting elements into the openings, and the retention wing portions are positioned externally at the back ends of the openings in a manner so as to prevent removal of the mounting elements from the openings.
