Abstract
A tap wrench comprising a handle portion and a chuck is provided with a joint arrangement that allows for axial misalignment of the handle portion and the chuck. The joint comprises a stem that extends from the chuck and provides four planar pins equidistantly spaced thereabout which slidably engage four slots equidistantly spaced about a central opening defined in the handle portion. The stem is retained within the central opening by the engagement of each pin in a respective slot. Oscillation of the stem within the central opening provides for the above-noted axial misalignment.
