The draw pad also includes a clamping surface that has a first force concentrating segment disposed circumferentially spaced apart from a second force concentrating segment, where each force concentrating segment includes a first arcuate groove and a second arcuate groove that is disposed concentric and radially spaced apart from the first arcuate groove.
