Sure-Loc™ Lock Ring
The Hornady Sure-Loc™ 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 die rings lock by jamming a set screw directly into the threads.
WRENCH FLATS: Remove and replace dies without pliers ruining the lock ring.
