ABSTRACT:
An attachment plate is used to attach insulation panels to building substrates using internal combustion cordless nail setting tools loaded with collating strips for feeding and holding nails in the tool magazine. The attachment plate has a washer and an annular chamber at a first end. A wall of the annular chamber is defined by a band of fingers. The interior of the attachment plate has a recess. The attachment plate second end has flexible tabs. The attachment plate is placed on a pilot and against a flange of a tool adapter. The attachment plate is pushed into the insulation panel such that the tool muzzle bends the fingers and passes through the same. When the tool is fired, a nail and nail collating ring are forced into and captured within the recess. The tabs bend against the substrate if the insulation panel is of less than nominal thickness.
