ABSTRACT:
A power driven wrench is disclosed that is used to fasten and secure helical spring wire connectors commonly known as WING NUTS or WIRE NUTS. The invention consists of a cone shaped plastic housing and a hexagonal shaft that extends outwardly from the bottom of the housing. The shaft is placed within a chuck of standard power tools such as power screwdrivers or variable speed drills. The housing is open at the top and hollow inside to receive the connectors. Two slots are placed within the walls of the housing to receive and hold the wings or flanges of the connectors. A number of ribs, concentrically placed around the inner wall of the housing, are also provided to engage ribs placed on certain types of connectors that have no flanges. The ribs prevent free rotation of the connector within the housing. A magnet is also embedded within the bottom of the housing. The magnet holds the connector within the housing by attracting the helical spring found in typical connectors. The housing is made of high strength, non-conductive plastic.
