## Abstract

The fastener comprises the combination of a gang nail plate and a clip. The plate is driven into the gypsum board panel to attach itself thereto. The clip connects with the plate and extends beyond its side edge. A screw or nail is driven through an aperture in the protruding end of the clip, to secure the panel to a supporting stud. The gang nail plate is known. It consists of a plate having tangs protruding from the inner face thereof and a slot-forming transverse member protruding from the outer face. The clip is a flat, rectangular, spring steel plate formed with an upwardly inclined inner end, a flat outer end, and a downwardly inclined central portion. The clip's inner end is wedged into the slot to tightly connect panel, plate and clip.

## Claims

### Claim 1

In combination:
a gypsum board panel having attached thereto adjacent a side edge thereof at least one gang nail plate, said plate having tangs extending from the inner face thereof and being embedded in the panel, said plate further having a transverse slot member extending outwardly from the outer face thereof, said slot member forming a clip-receiving slot extending in a generally horizontal direction;
a stiff, resilient clip, said clip comprising
a first end portion which lies generally flat against the panel and extends beyond the latter's side edge.
a second end portion which is upwardly and angularly disposed away from the panel, the end of said second end portion being wedged in the slot,
and a central portion extending upwardly and angularly from the panel and connecting said end portions, said second end portion and central portion combining to provide a V-shaped configuration with the apex directed away from the panel;
said first end portion forming an aperture in the section extending beyond the panel side edge;
a support member;
and means extending through the aperture into the support member to tie the clip and support member together;
whereby the clip wedges against the transverse slot member and thus the plate and clip remain tight together and provide, in conjunction with the tie means, a firm connection between the panel and support member.
