Abstract: A fastener driver includes a pusher assembly slidably coupled to a magazine assembly. The pusher assembly includes a first portion and a second portion that are selectively movable relative to each other. The pusher assembly is adjustable between a first state in which the first portion and the second portion are configured to move together in unison toward the channel, and a second state in which the first portion moves relative to the second portion toward the channel. A dry-fire lockout assembly includes a blocking member coupled to the magazine assembly or the nosepiece assembly, and a lockout member selectively engageable with the blocking member for moving the blocking member from a first position and a second position. The pusher assembly is configured to transition from the first state to the second state after a predetermined number of fasteners remain in the magazine assembly.

Abstract: A fastener driver includes a housing, a cylinder supported by the housing, and a moveable piston positioned within the cylinder. A driver blade is attached to the piston and movable therewith between a top-dead-center position and a driven or bottom-dead-center position. The driver blade includes a body having a first side and an opposite, second side with the driving axis passing therebetween, a plurality of teeth extending from the first side of the body, and a plurality of projections extending from the second side of the body. The body and the projections are bisected by a common plane. The teeth extend at an oblique angle from the first side of the body relative to the common plane.

Abstract: A powered fastener driver includes a housing, a nosepiece having a fastener driver channel from which fasteners are discharged into a workpiece, a driver blade, a workpiece contact element, and a pusher mechanism. The powered fastener driver also includes a dry-fire lockout mechanism having a lockout lever movable between a bypass position and a blocking position and a last fastener holding member configured to engage a fastener within the fastener driver channel. The lockout lever is configured to engage the fastener within the fastener driver channel. The last fastener holding member biases the fastener within the fastener driver channel toward an inner surface of the fastener driver channel to inhibit the fastener from falling out of the fastener driver channel.
