Infinity Tools SuperNut Table Saw Arbor Nut, For Standard 5/8"–12 TPI Acme-Threaded Arbors Only

Fully Engaged Threads for Full-Stack Dado Sets & Faster Blade Changes

The Infinity SuperNut Arbor Nut is a smarter, safer upgrade for table saws with a standard 5/8"–12 TPI Acme-threaded arbor, including SawStop and most full-size cabinet saws.

There is a right-handed as well as a left-handed thread option, made to fit many brands of table saws. READ CAREFULLY BELOW TO CONFIRM WHICH ONE YOU NEED. 

A Better One-Piece Arbor Nut Design

Traditional arbor nuts use a separate nut and flange—easy to drop inside the saw and often too bulky for wide dado stacks. When cutting dados, these parts can take up valuable arbor length, reducing thread engagement and compromising safety.

The SuperNut solves these issues with a compact, one-piece design that integrates the flange and nut as a single piece. There is nothing to lose, nothing to fumble, and you get full thread engagement even with wide dado sets. The thread extends through the entire nut/flange system. This is the smarter nut design! 

Compact Profile, Maximum Clearance

Designed specifically for 5/8" Acme-threaded arbors, the SuperNut measures just 3/4" thick, providing added clearance under the throat plate. It works with your saw’s factory 1-1/16" hex wrench and allows a full dado stack to tilt to 45° at full blade height without contacting the throat plate.

Unlike two-piece unthreaded flange and threaded nut systems, here the threads extend through the entire sytem, ensuring a secure, confident hold on standard blades and full-width dado stacks alike.

Faster Blade Changes, Fewer Headaches

With the flange permanently attached, dropped hardware becomes a thing of the past. Blade changes are quicker, easier, and more reliable—keeping your workflow smooth and your focus on the cut.

Key Features

• Integrated design – Nut and flange are milled as a single piece.  There is no separate nut to accidentally drop into the saw
• Proper fit – For 5/8" Acme-threaded arbors that use 1-1/16" arbor nut wrenches
• Both Right-Hand and Left-Hand models are available (each sold separately)
• Slim profile – Only 3/4" thickness for increased internal clearance
• Dado ready – Maintains full thread engagement with wide dado stacks

Brands That Generally Use Standard Right-Hand Threads

These manufacturers almost always use conventional right-hand arbor nuts:

• SawStop  
• Delta (modern models) 
• Powermatic (modern models) 
• Jet 
• Grizzly 
• Laguna 
• Harvey 
• DeWalt 
• Bosch 
• Makita 
• Ridgid  
• Skilsaw  
• Festool  
• General International

Left-hand threaded arbor nuts are not common on modern table saws. The vast majority of table saws—whether cabinet, contractor, hybrid, or jobsite models—use standard right-hand threads on the arbor nut, even though the blade rotates in a way that continually tightens the nut during operation. 

Table saws known to use left-hand threaded arbor nuts: 

• Delta 34-338 10" Contractor Saw
• Delta 34-341 Contractor Saw
• Delta 34-348 10" Contractor Saw
• Delta 34-388 12" Contractor Saw
• Delta 34-400 10" Bench Saw
• Delta 34-402 10" Bench Saw
• Delta 34-405 10" Right-Tilt Unisaw
• Delta 34-410 Contractor Saw
• Delta 34-425 Bench Saw
• Delta 34-426 10" Bench Saw
• Delta 34-429 10" Bench Saw
• Delta 34-430 10" Bench Saw
• Delta 34-441 Contractor Saw
• Delta 34-444 Contractor Saw
• Delta 34-474 Contractor Saw
• Delta 36-957 Contractor Saw
• Delta 36-960 Contractor Saw (same arbor family)
• Delta Early right-tilt Unisaws Various models using the same arbor assembly
• Older Craftsman table saws (primarily some models built by Emerson Electric)
• Some older Delta/Rockwell saws  
• A few vintage Walker-Turner and Powermatic machines  

How to tell which you have if you're unsure

1. Check the owner's manual.
2. Look at the parts diagram—the arbor nut is often identified by its thread direction.  
3. If the arbor thread is visible, compare it to a standard bolt.
4. Never force the nut. If it tightens when turned counterclockwise, it is likely a left-hand thread.  
5. The old adage: Lefty Loosey/Rightey Tighty applies.  You're already used to removing your arbor nut when changing blades on your saw.  If you spin to the right to tighten the nut you need a right-hand nut.  BUT, if you spin to the left to tighten the nut then you need a left-hand nut.
