A fastener-driving tool 10, useful to fasten a dimpled membrane 30 to a foundation wall 40, via a fastener 12 and a polymeric plug 20, comprises a nosepiece 14, means (driving ram 16) for driving the fastener 12 from the nosepiece through the polymeric plug and through the dimpled membrane into the foundation wall, an actuating member 18 mounted movably on the tool and movable thereon between an extended, tool-disabling position and a retracted, tool-enabling position, and a workpiece-contacting probe 100 mounted to the actuating member so as to be conjointly movable with the actuating member. The probe includes a plug-holding member 110 adapted to hold the plug as the fastener is being driven. Member 110 has a tubular wall 112 defining a recess 120 adapted to receive the plug. Member 110 has at least one pointed element 130 having a point projecting inwardly from the tubular wall so as to press against the plug when the plug is received in the recess. The tubular body may include at least one permanent magnet (not shown) positioned at one side thereof, the plug-holding member being held by the magnet when mounted to the tubular body, and the magnet being adapted to hold a steel washer when the plug-holding member is removed.
