ABSTRACT:
In one embodiment, there is provided an axial nut starter having a nut engaging member which can be used with a wide range of nut sizes. The nut engaging member is in the form of a stepped series of stacked, coaxially aligned cylinders. The base, or the largest cylinder, of the nut engaging member is attached to an elongated handle. The top, or the smallest cylinder, of the cone is inserted into the nut until the wall of one of the cylinders frictionally engages the threads of the nut and the face of the nut shoulders against the top of the next larger cylinder. Unitary rotational movement of the handle and the nut engaging member starts the nut on the fastener. In another embodiment, an offset nut starter is provided which permits the starting of a nut on a fastener when it is impossible to reach the fastener along its axis. This embodiment comprises an elongate tool having the nut engaging member rotatably disposed at one end thereof, with the major axis of the nut engaging member orthogonal to the major axis of the tool. Driving means located on the tool, remote from the nut engaging member and operatively connected to the nut engaging member permits remotely rotating the nut engaging member so as to advance the nut onto the fastener.
