Abstract: An apparatus for removing a fastener having a cylindrical aperture is described. The apparatus includes a base, a camshaft, a sleeve and a cartridge. The camshaft includes lobes that extend from a camshaft top surface to a camshaft bottom surface. The cartridge includes a cartridge top surface, a cartridge lip and a plurality of jaws. Each jaw includes a jaw counterclockwise outer frictional surface, a jaw counterclockwise inner cam surface, a jaw clockwise outer frictional surface and a jaw clockwise inner cam surface. The cartridge is fixedly coupled to the sleeve and the cartridge interfaces with the camshaft. Additionally, the jaw inner cam surface interfaces with the camshaft cam profiles. The jaws rotate and engage the walls of the fastener cylindrical aperture.

Abstract: An apparatus for removing a nut is described. The apparatus includes a housing, a cage, and a canted coil spring. The housing has a top surface, an interior sidewall, and a bottom surface. The interior sidewall defines an orifice that extends from the top surface to a lip. The interior sidewall includes a three-lobed cam and a groove. Each lobe has a lobe center line, a counterclockwise cam inner surface on one side of the lobe center line, and a clockwise cam inner surface on the opposite side of the lobe center line. The canted coil spring is received by the groove of the interior sidewall and the groove of the cage. The canted coil spring rotatably couples the cage to the housing. During nut removal, the housing rotates counterclockwise relative to the cage. The cage rotates counterclockwise to engage the nut, and the cage interfaces with the interior sidewall.
