This is exactly why I use a " Blue Point " as I mentioned previously. The jaws can reach the bottom of the stud but unlike a Stilson which is only holding the stud on two opposing faces, the three jaws are arranged in radial symmetry exactly as a drill chuck. Unlike a drill chuck which uses a key, the B.P. jaws are clamped by means of a spanner exerting immense force, so reducing twist and ultimate breakage of the stud.
