Tool sets with tap wrenches

Tap wrench

— a device for turning the interchangeable nozzles installed on it. Classic cranks have a T-shape, with a long handle and a short perpendicular ledge, on which the nozzle is installed; however, there are other design options. Also note that in some sets the wrench is combined with a rigid extension (see the relevant paragraph): the extension tube can have fasteners for installing nozzles and, if necessary, be used as a wrench.
