Hornady Deluxe Die Wrench 396495 is the ultimate 4-in-1 reloading tool for your Lock-N-Load AP or single stage Classic press. This Hornady reloading tool holds the shell plate and keeps it from rotating while you change plates and tighten the main press screw. The Hornady Deluxe Reloading Die Wrench also adjusts the tightness of the spindle lock and the lock rings, and the reloading tool can tighten or loosen the die flats. No reloading bench should be without the Hornady Deluxe Four in One Die Wrench.
