Hornady 044000 Sure-Loc Lock Ring 7/8"x14 Threaded Dies

Sure-Loc Lock Rings let you make precise adjustments of all standard 7/8"-14 dies and accessories. It clamps around the whole die, and can't damage the threads. It applies constant pressure across the threads to hold the ring in place. (Most other die rings lock by jamming a set screw directly into the threads.) Wrench flats allow for removal and replacement of dies without pliers ruining the lock ring.
