The thoughtfully designed JONMAC multi-tool allows a number of tasks to be carried out on most domestic boiler pumps. A long magnetic tipped shaft accommodates interchangeable tips and allows easy access to the difficult to reach underside nuts on the pump head. The tool is supplied with two double-ended tips, to suit 4, 5 and 6mm hex pump head nuts and a 4mm flat end to fit the slot on the rotor shaft. An ergonomic handle incorporates a recess to hold one of the tips and a semi-circular end to fit the vent plug cap. Read product review from Amazon Customer Reviews.
