ABSTRACT:
This unique cylinder shaped toggle type fastener may be used with either a bolt having a saddle type head or a bolt having a saddle type nut. The shape of the slotted toggle having one end tooth shaped allows it to be easily tipped into a saddle from the parallel position with the shank to the perpendicular position from the shank of the bolt or screw after being inserted through the hole in the material it is to be fastened to. The unique shape also leaves a flat V-shaped surface that abutts to the inside of the material. The design of the toggle eliminates the necessity of any pins giving the toggle much greater strength than other varieties. This type of fastener may be manufactured out of any kind of metal, plastic or nylon.
