In a fastener-driving tool, which may be a pneumatically powered or combustion-powered pin-driving or nail-driving tool, and which comprises a nosepiece and is adapted to drive a fastener from the nosepiece, through a workpiece, into a substrate, a workpiece-contacting probe comprising two permanent magnets is mounted to the nosepiece for magnetically and releasably holding a washer plate made of magnetizable steel between the nosepiece and a workpiece. Thus, a fastener driven from the nosepiece is driven through a washer plate held by the workpiece-contacting probe, through a workpiece, into a substrate. The workpiece-contacting probe adapts the fastener-driving tool particularly but not exclusively for fastening metal lath to concrete walls, concrete blocks, or other building substrates.
