ABSTRACT:
A fastener comprising a threaded stud and a rectangular nut having raised flanges is disclosed. Raised flanges enable passing the fasteners in a curvilinear dispensing track. The rectangular nut resides in a channel in a threshold device and is restrained against rotational movement. The threaded stud includes a flat head adjustable in a plurality of positions which, in turn, enables positioning of the threshold.
