Hornady Zip Spindle Straight Wall & Pistol Kit 43402 is a convenient way to get more out of your sizing die. This Hornady reloading tool converts Hornady New Dimension sizing die to Hornady's threaded spindle Zip Spindle design. This model of the reloading tool is designed to convert straight wall and pistol sizing die. Hornady has included a threaded spindle and a threaded spindle collet in the Hornady Zip Spindle 1pc Kit.
The Hornady zip spindle kit is the ideal kit for updating your older Hornady sizing dies to utilize the new threaded spindle design. The zip spindle design on all full length size dies positively locks to eliminate slippage. A Series of light threads cut on both the spindle and spindle collet allows you to make incremental adjustments by turning the spindle or you can easily zip it up or down for larger movements. This kit includes a new threaded spindle and a threaded spindle collet. To install, remove the non-threaded spindle, collet, and expander ball from the existing die. Re-attach the existing expander ball to the new spindle, and install the threaded spindle and threaded collet. If the spindle on the expander die is already threaded, then this kit is not necessary.
