Abstract
A tool for applying fasteners to fasten an article to the workpiece. A compressible foot is provided to limit the drive distance of a plunger to position dependent upon the thickness of the article. A drive groove in the tool provides support for the fastener until it is driven into the workpiece. The fastener may be a plastic staple and multiple driving strokes may be used to drive the staple into the workpiece. A retainer activated by the compressible foot may be utilized to prevent the advancement of the next staple to the drive position while multiple drive strokes are being used.
