A plate on the jaw is also recessed and has flats to engage flats on the mandrel to hold the latter against rotation during removal of a mandrel screw. A pin supports the plate for limited rocking motion to facilitate mandrel entry into the recess. The holder may pivot also for the purpose of mandrel entry into the plate recess.
