The Hornady Custom Grade New Dimension Die Zip Spindle Kit is a great way to upgrade your previous Hornady Sizing dies to the new threaded spindle design. On the spindle and collet of the Zip Spindle, a sequence of light threads are cut. This eliminates spindle slippage, and makes tightening the spindle lock a breeze when making adjustments.
This kit includes a new threaded spindle (decapping rod) and a threaded spindle collet (portion of the kit that tightens the threaded spindle so it will not slip in the die). this kit does not include a decapping pin retainer or expander ball. Reloaders must use the decapping pin retainer and expander ball that is on their die set.
