Smart, simple, secure—lock rings reimagined.

The Lee Ultimate Spline Drive Lock Ring 4-Pack takes a basic reloading accessory and turns it into something brilliant. Designed for precision reloaders who demand tools that just work, these anodized aluminum lock rings clamp tighter, grip better, and install easier than anything else on your bench.

Each pack includes four premium lock rings in red, white, blue, and gold—easy to spot, even easier to use. The spline-drive outer surface provides a no-slip grip, while the cross-bolt design offers a vice-like hold without damaging your dies. No more stripped set screws or worn-out threads.

Lee also includes their signature "O" rings, which lock everything in place without the need for over-tightening. Finger-tight in, finger-loose out—it’s that easy. Compatible with all 7/8 x 14 threaded Lee reloading dies and presses, and works flawlessly with the Lee lock ring wrench for tight setups on turrets or tool heads.
