Abstract: A spud tool for use by a plumber to install and to remove plumbing feed water spuds includes an elongate tubular socket-like body internally recessed and provided with wrenching flats; and a captive coaxial stem having a cruciform head disposed both axially-movably and relatively-rotationally within the recess of the socket-like body. The stem at an end opposite to the cruciform head carries a handle portion for application of manual torque, and the handle portion is slidably movable from side-to-side of the stem in order to allow a wrench head to be slipped along the handle portion and onto the stem in order to achieve driving engage with the socket-like body.
