An electrical outlet box is molded of plastic and includes push-in type screw receiving openings each of which is defined by rigid first and second walls having opposed semi- cylindrical faces mounted in spaced and axially aligned relationship to produce a generally cylindrical passage open at an outer end. Threads are formed about the interior of the cylindrical passage. In a first embodiment, the first wall is supported and carried substantially entirely by a resilient support wall lying in a plane generally perpendicular to the axis of the cylindrical passage. The support wall is mounted in cantilever fashion at a location spaced radially from the axis of the cylindrical passage so that the first wall can resiliently deflect away from the second wall when a screw is pushed axially into the passageway. In a second embodiment, both the first and second walls are mounted by resilient support walls to allow deflection in the manner described.
