Hornady Sure-Loc Lock Ring

Hornaday Sure-Lock Lock Ring lets you make precise adjustments of all standard 7/8"-14 dies and accessories. Lock Ring: Clamps around the whole die. Can't damage the threads. Applies constant pressure across the threads to hold the ring in place. Most other rings lock by jamming a set screw directly into the threads. Wrench Flats: Remove and replace dies without pliers ruining the lock ring.
