Bondhus 33020 T20 Weighted T Hex Key – IDEAL FOR NOVA PRO-TEK JAW CHANGES WITH T20 STAR SCREWS

The Bondhus T20 Weighted T Hex Key is a HUGE upgrade from the stock star key for fastening the jaws on that comes with the Pro-Tek kits.  The handle is weighted, so you can start the screw, spin the hex portion between your thumb and forefingers to quickly run the screw in and out,  then just lock with the T-handle.  This will probably halve the time you spend changing jaws.
