Abstract: An autofeed attachment designed for mounting to a manual-feed screwgun that has a recessed channel on the exterior surface near a protruding flange. The autofeed attachment has at least one movable plate that is forced inward by a ramp structure on the interior surface of a rotatable collar. When the collar is rotated in a predetermined direction, the ramp surface acts to force the movable plate toward the interior, until that movable plate comes into contact into the recessed channel on the screwgun. Once that has occurred, the autofeed attachment will now be locked into place into that recessed channel and behind a protruding flange of the screwgun. The movable plate(s) is positioned between two retainer structures that are spaced-apart from one another, and create a gap through with the at least one movable plate can move during the locking, and later unlocking operations, by twisting the rotatable collar.

Abstract: A pneumatic fastener driving tool is configured to drive a threaded fastener using both linear and rotational motion. The tool allows a fastener to first be driven linearly, without rotation, through a surface material and into a substrate material, preferably to a depth that causes the fastener to at least pierce the substrate material.

The tool has sufficient linear force to drive a fastener into relatively hard substrate materials, such as steel studs, and has a stationary air motor assembly to reduce recoil generated during the driving process. The tool further comprises a gear reducer assembly that uses a compound planetary gear in order to reduce the overall length of the tool.
