Powered fastener driver

A fastener driver comprising:

• a magazine configured to receive fasteners;
• a nosepiece including a fastener driving channel from which consecutive fasteners from the magazine are driven and a nail receiving aperture through which the fasteners pass from the magazine into the fastener driving channel to be fired, the fastener driving channel defining a firing axis, the nail receiving aperture being partially defined by a first protrusion extending from the nosepiece and a second protrusion extending from the nosepiece, the first protrusion and the second protrusion of the nosepiece positioned on opposite sides of the nail receiving aperture, each of the first protrusion and the second protrusion of the nosepiece having a length extending parallel to the firing axis and a height extending perpendicular to the firing axis;
• and
• a workpiece contact element movable relative to the nosepiece between an extended position and a retracted position, a portion of the workpiece contact element slidably positioned within the fastener driving channel, the portion of the workpiece contact element having an aperture extending therethrough in which the fasteners pass from the magazine through the aperture into the fastener driving channel of the nosepiece to be fired, and the portion of the workpiece contact element further including a first protrusion extending from the portion of the workpiece contact element and a second protrusion extending from the portion of the workpiece contact element, the first protrusion and the second protrusion of the workpiece contact element positioned on opposite sides of the aperture and at least partially defining the aperture, each of the first protrusion and the second protrusion of the workpiece contact element having a length extending parallel to the firing axis and a height extending perpendicular to the firing axis,
• wherein the nail receiving aperture is aligned with the aperture of the workpiece contact element, and wherein the fasteners pass from the magazine through the nail receiving aperture and the aperture and into the fastener driving channel of the nosepiece to be fired, and
• wherein the first protrusion and the second protrusion of the workpiece contact element are aligned with the first protrusion and the second protrusion of the nosepiece, respectively, to collectively define at least part of a guiding assembly configured to guide each of the fasteners along the portion of the workpiece contact element within the fastener driving channel as each of the fasteners is being fired into a workpiece.
