The Woodpeckers Dado Nut is a clever solution for SawStop table saw users who want to use a full 3/4″ dado stack. When installing a dado stack, there’s often not enough shaft length to accommodate both the arbor washer and the arbor nut. Leaving off the washer can compromise cut quality. The Dado Nut merges the arbor washer and nut into one integrated unit, ensuring stability and full thread engagement. It’s a simple replacement for the factory arbor washer and nut, using standard SawStop arbor wrenches.
