The ZERO Locking Die Rings are designed for improved consistency with a large diameter for better turret head contact and more thread engagement for squaring the die to the press.
Each pack comes with multiple 17-4PH stainless steel rings with a black nitride finish and includes a wrench, with variations available for different die sizes and pack configurations.
The rings feature an internal wrench engagement for easier tightening without the need for external tools, and are precision-manufactured for square alignment of the die.
