ABSTRACT:
A fastener, such as a nail or staple, includes a fastener body having an impact surface and a plug of filler material joined to the impact surface. The plug of filler material fills the hole made by the fastener body when the fastener is driven into a workpiece. Many types of fasteners can be used, such as nails and staples. In the case of a nail, the plug of filler material would be joined to the nail head. In the case of a U-shaped staple, the plug of filler material would be joined to the cross member joining the staple legs. The filler material can be a wide variety of materials such as wood putty, acrylic sealant, fiberglass resin fillers, epoxy adhesives, and plastic.
