A fastener-driving tool has a cam-actuated pneumatic switch mechanism system operatively incorporated thereon which is adapted to control the timed driving or discharge of fasteners out from a hand-held fastener-driving tool and into a substrate at predeterminedly spaced positions with respect to each other. The arrangement is particularly adapted for use in connection with the driving of fasteners into corner regions of structural workpieces, although the same may also be used to drive fasteners into flat planar surfaces.
