I find the easiest way to assemble the jewelry pieces is to insert the bolt through the drilled holes of the components you want to cold connect. Place the piece flat on the table. Slip the washer onto the bolt. Screw the nut onto the bolt a couple of threads. Use the EZ socket wrench to completely screw the nut into place. Use another socket wrench attached to the hex head to tighten. Saw off the protruding bolt end. File..
