Abstract
Abstract A fastener clip is adapted to be pushed onto an edge of sheet materials of varying thicknesses. The clip has two legs. The first leg has a U-shaped elongated tongue cut from it and bent towards the second leg to frictionally engage a sheet material disposed between the two legs; the second leg has an integral threaded barrel for receiving a bolt. The U-shaped tongue is formed with offset bends to allow the tongue to yield when the clip is mounted on a thick sheet material.
