If you’ve tried to put a full 3/4" dado stack on your SS Table Saw, you know the problem; there's simply not enough shaft to install both the arbor washer and the arbor nut. To get the best cutting performance, the washer is pretty much a necessity. Leaving it off can distort the blade and compromise cut quality. The engineers at Woodpeckers have developed a clever solution; a combination arbor nut and washer that doesn’t take up any more room than the original nut by itself. We call it the Dado Nut.
Full Thread Engagement with a 3/4" Stacked Dado
Dado Nut merges the arbor washer and arbor nut into one integrated unit. The threads extend almost completely through the arbor washer and the nut is conveniently retained within the washer. Now you have the stability of a carefully machined arbor washer AND full thread engagement of the arbor nut when using a full dado stack.
Dado Nut doesn't require anything new or different for install. Use it in place of the factory arbor washer and arbor nut (uses factory wrenches). Dado Nuts are turned on our CNC Swiss lathes and held to strict tolerance for flatness and thread accuracy. Made from a special heat-treated steel that holds up to repeated installation and removal. Since the washer and nut are secured to each other, blade changes go smoother and faster. When you take the dado blade off and put your normal saw blade back on, you'll probably decide to use your Dado Nut for that, too…it's just that good. Dado Nut is threaded with 5/8"-12 tpi right-hand Acme threads. This will fit some other saws in addition to SS. It will not fit any saw with left-hand threads, which include most saws where the blade tilts to the right, rather than left.
SS Model fits most SawStop Table Saw models.
ICS model fits SawStop ICS (Industrial) models built before 2014 that have a slightly different thread.
Like all Woodpeckers products, Dado Nut is machined and inspected in the USA.

The Dado nut is durable, saves space, and has fantastic functionality. When I get the correct part the time savings in changing blades will be extreme and easy. Thank you for making this part. I received two from Amazon and one from Woodpecker, I did not receive the ICS-10, I only received 3 SSs which are right-handed threads, and my saw is left-handed threads, so Woodpecker does not sell ICS-10s, and has a great picture on line of the ICS-10, and they do sell ICS-10 bags, but not the ICS-10 parts. I am dealing with this now. This is not Amazon's fault they are just an excellent seller, not a manufacturer. Keep up the good work so far Woodpecker. If I ever get a right-handed arbor saw this will work.

I ordered this hoping it would work on my old Powermatic 66 and it fit perfect. I'm now using it for all my blades not just the dado stack.

Very good and convenient nut! Much easier to install and remove than the two piece nut provided by Sawstop.

Works nice for my DADO blades. Little expensive but I wanted this for the design of flange and nut in one so I don't have to fish it out of my saws base all the time if I fumble with my standard nut I had. Keeps my DADO stack where it belongs.

If you run a dado stack on a Sawstop then this is a mandatory item. The original SawStop arbor nut is useless for a dado stack. I love SawStop but they came up short. Woodpeckers arbor nut is many times better.
