Abstract: A tool holder combination for use with a perforated support panel includes an elongate plate having front and rear surfaces and at least two panel engaging hooks pressed from and projecting from the rear surface adjacent the opposed ends for engagement with adjacent perforations in the support panel. The plate includes an integral, offset center portion disposed parallel to the plane of the front surface of the plate and which occupies approximately fifty percent of the overall length of the plate. The offset center portion also contains a through screw receiving aperture adjacent one end of the offset portion and the combination includes a self-threading, tapered screw having a relatively deep thread which is intended to pass through the screw receiving aperture and engage the edge of a perforation on the support panel when the panel engaging hooks are in engagement therewith to draw the plate toward the support panel and securely anchor it thereon.
