ABSTRACT:
A caged nut for mounting a threaded nut on a surface comprises a housing of box-like structure enclosing an internally threaded nut. The housing is formed of a single blank of sheet metal and comprises a square central section with a clearance hole therethrough and two end walls and two side walls extending at right angles from the respective opposed edges of the central section. Mounting flanges extend outwardly at right angles from the ends of the end walls, and locking flanges extend inwardly from the ends of the side walls. Locking tabs extend outwardly from the sides of the locking flanges and engage openings in the mounting flanges. The engagement of the locking tabs in the openings in the mounting flanges prevents the side walls from spreading outwardly due to a rotational force being placed on the nut.
