A power actuated tool for driving a fastener such as a pin into a substrate such as steel or concrete comprises a driving piston ( ) which is driven forwardly within the barrel ( ) of the tool upon firing and is automatically reset in response to cocking of the tool prior to the subsequent firing. Resetting of the piston takes place by thrusting the piston ( ) rearwardly during cocking by means of a spring-loaded gripper device ( ) energized during cocking.
