A non-metallic electrical wiring box having a fast set screw mounting socket for mounting electrical devices inside the box. The box includes a pair of side walls, a pair of end walls, a back wall, a front opening and one or more fast set screw mounting sockets in each end wall, or connected to each end wall, for receiving a mounting screw. Each socket includes: a socket wall, preferably a cylindrically-shaped wall, an interior wall surface, a first end, a second end and a mid-region. The first end corresponds to the front opening of the box and the mid-region is between the first and second ends of the fast set screw mounting socket. Each socket also has a center slot in the socket wall, which preferably bisects the socket wall and extends from about the mid-region to the second end of the socket and defines two or more flexible socket wall sections.
