The Woodpeckers Dado Nut addresses a common challenge faced by woodworkers using SawStop table saws: fitting a full 3/4″ dado stack. Traditionally, there’s insufficient shaft length to accommodate both the arbor washer and the arbor nut, leading to compromised cutting performance. The Dado Nut ingeniously combines the arbor washer and nut into a single integrated unit, solving this problem.

Here are the key features of the Dado Nut:

• Full Thread Engagement: The threads extend almost completely through the arbor washer, and the nut is conveniently retained within the washer. This ensures stability during dado stack usage.
• Precision Machining: Woodpeckers manufactures the Dado Nut using state-of-the-art CNC Swiss lathes, maintaining strict tolerances for flatness and thread accuracy.
• Heat-Treated Steel: Crafted from special heat-treated steel, the Dado Nut withstands repeated installation and removal.
• Easy Installation: No need for anything new or different—simply replace the factory arbor washer and nut with the Dado Nut using standard SawStop arbor wrenches.
• Blade Changes Made Easier: Since the washer and nut are secured to each other, switching between blades becomes smoother and faster.
• Compatibility: The Dado Nut features 5/8″-12 tpi right-hand Acme threads, fitting some other saws in addition to SawStop. However, it won’t work with saws that have left-hand threads (typically those where the blade tilts to the right).

Woodpeckers president Rich Hummel originally developed the Dado Nut for personal use, recognizing the importance of avoiding direct contact between the arbor nut and the dado blade. Now available as a product, the Dado Nut enhances safety, precision, and convenience for woodworkers. Whether you’re tackling dado cuts or switching back to a regular saw blade, the Dado Nut proves indispensable.
