The Lyman Brass Smith Die Wrench (Lyman part no. 7631250) is a single stainless steel tool built to fit every lock nut you will run into on Lyman dies: die body expander plugs, seating screw lock nuts, and decapping rod lock nuts, plus the lock nuts used on Lyman Pro dies and Dillon dies. Made from rust-resistant stainless steel, its closed-end design offers added strength with thinner side walls, which lets it fit into tighter spaces between dies than a bulkier wrench. Five separate openings on the tool cover the 1-3/16 inch, 1 inch, 3/4 inch, 5/8 inch, and 3/8 inch lock nut sizes used across Lyman and Dillon dies, so one wrench replaces a whole set of loose tools.
