The Woodpeckers Dado Nut is a specialized arbor nut for SawStop table saw dado setups. This is a dado arbor nut designed for securing a dado stack with fuller thread engagement on SawStop arbors. Model DADONUT-SS is aimed at woodworkers and shop users who want a cleaner, more confidence-inspiring way to mount a dado stack instead of living with minimal thread contact on the factory setup.

The big deal here is simple: when you stack dado blades, arbor thread length becomes the limiting factor. The Woodpeckers Dado Nut is built to address that problem by helping achieve full thread engagement on SawStop arbors. On the job or in the shop, that matters because the arbor nut is what keeps the stack locked down. More usable thread contact means a more secure setup when you're cutting dados, grooves, and joinery.

Woodpeckers did not treat this like a generic replacement nut. The design integrates a specialized arbor nut with a precision-machined arbor washer, which is the kind of detail serious table saw users notice right away. Instead of piecing together an improvised solution, you get a purpose-built part made specifically for this application. That focused design is the value here. It solves a narrow problem that shows up the minute you start using a wider dado stack.

From the product images, this setup is shown delivering full thread engagement on a 3/4 inch dado stack on a SawStop table saw. For woodworkers cutting cabinet dados, shelving joinery, casework grooves, and tenon shoulders, that is the difference between a setup that merely fits and one that feels properly engineered. If your work depends on repeatable dado cutting, the hardware holding the stack matters just as much as the cutters themselves.

The Woodpeckers Dado Nut is also the kind of accessory that makes sense for users who already invested in a premium saw and want the same level of thought put into the accessories around it. It is Made in USA and marked patent pending, which tells you this is not a commodity part. It is a shop-specific solution for a known compatibility issue with dado stack mounting on SawStop equipment.

Who should buy it? SawStop owners who regularly run dado blades and want a better arbor nut solution. If you mostly live on a standard blade and only cut the occasional groove, this may be a nice-to-have. If you build cabinets, drawers, built-ins, or furniture and swap to a dado stack often, this is exactly the sort of small upgrade that saves aggravation and makes your table saw setup feel sorted out.
