The Hornady Zip Spindle Kit for Straight Wall and Pistol cartridges upgrades older Hornady Custom Grade sizing dies to the later threaded “zip” spindle configuration. The lightly threaded spindle reduces spindle slippage and makes tightening the spindle lock easier during adjustments. This kit is intended to retrofit Hornady straight-wall and pistol-caliber Custom Grade sizing dies to the threaded spindle standard.
Key Specifications

- The kit includes a threaded spindle collet to secure the spindle in the die.
- The kit includes decapping pin(s) for primer removal as part of the assembly.
- The kit may include a spindle lock and decap pin retainer depending on the production variant.
- Compatibility is with Hornady Custom Grade straight-wall and pistol sizing dies.
- Installation requires removal and replacement of the existing non-threaded spindle, collet, and expander ball and reattaching the expander ball to the new spindle.
- All die sets shipped in 2006 and later are produced with the threaded (zip) spindle and typically do not require this retrofit.
- The zip spindle features light threads cut on the spindle to reduce slippage and ease adjustments.
This Zip Spindle Kit offers a straightforward retrofit path for shooters who prefer the threaded spindle interface on older Hornady Custom Grade sizing dies. It simplifies fine adjustments and addresses spindle slippage while maintaining the die’s original expander and sizing functionality.
