Are all table saw arbor nuts the same size?
No. Arbor nuts are not universal; the nut’s thread size and direction must match the arbor shaft on your Craftsman 10321040 bench saw. Many 10-inch table saws use a 5/8-inch arbor for the blade bore, but that does not guarantee the arbor nut is the same across brands or even across models.
What actually has to match
When you replace an arbor nut, these details must match your saw’s arbor:
- Thread diameter and pitch (for example, 5/8-inch diameter can still have different thread pitches)
- Thread direction (right-hand vs left-hand thread)
- Nut style (standard hex nut vs flanged nut vs washer-and-nut setup)
- Arbor length and washer stack-up (so the nut fully engages the threads)
- Blade and flange fit (the nut must clamp the blade securely without bottoming out)
Quick reference: common table saw patterns
These are common patterns across many table saws; use them as a starting point, then confirm what your 10321040 uses.
| Saw/blade class | Common blade bore | Arbor nut “universality” |
|---|---|---|
| 10-inch table saw | 5/8 in | Low; nut threads vary by model |
| 12-inch table saw | 1 in | Low; nut threads vary by model |
| Jobsite/compact saws | 5/8 in (often) | Low; some use unique flanges/nuts |
How we recommend confirming the correct arbor nut
Because this model page does not include a model-specific arbor nut listing, confirm the arbor nut specs before ordering:
- Unplug the saw and remove the blade guard and throat plate
- Remove the blade and inspect the arbor threads for damage or flattening
- Measure arbor thread diameter with calipers (or compare to known nuts)
- Check whether the nut loosens in the same direction the blade spins (many saws use a thread direction that resists loosening)
- Match the replacement to your exact model number using how to find your appliance model number (and what it means for parts)
Why it matters
A mismatched arbor nut can strip threads, fail to clamp the blade, or loosen during cutting. Using the correct thread size, pitch, and direction keeps the blade secure and helps the arbor bearings and flange run true.

Can you use an 8 inch blade on a 10 inch table saw?
Yes, you can use an 8-inch blade on a 10-inch table saw like the Craftsman 10321040 as long as the blade fits the arbor and you use it for the right type of cut; you will lose maximum cutting depth, and you must keep the guard and riving knife aligned for the smaller blade.
When an 8-inch blade makes sense
An 8-inch blade is commonly used for non-through cutting setups (like many dado-style operations) or when you simply need a smaller diameter for a specific task.
- You need less cutting depth than a 10-inch blade provides
- You are doing joinery where the blade does not cut all the way through the workpiece
- You want a lighter cut with potentially less load on the motor
- You understand that the blade guard may not cover the blade correctly with a smaller diameter
Fit and safety checks (do these before you run the saw)
The two critical compatibility points are arbor fit and safe guarding.
- Match the arbor hole size to your saw’s arbor (commonly 5/8 inch on many 10-inch saws)
- Confirm the blade’s rated RPM meets or exceeds the saw’s no-load RPM
- Verify the flange and arbor nut fully clamp the blade (no bottoming out)
- Re-check riving knife or splitter alignment; it must track the blade’s kerf
- Hand-spin the blade to confirm it clears the throat plate and any inserts
What changes vs a 10-inch blade
| Item | 10-inch blade | 8-inch blade |
|---|---|---|
| Max cutting depth | Higher | Lower |
| Guard coverage | Designed to fit | May not fit correctly |
| Kickback control (riving knife) | Typically straightforward | Must be re-checked carefully |
| Best use | General ripping/crosscutting | Specialty cuts, reduced depth work |
Why it matters
Using the wrong blade size or an improperly guarded setup increases the chance of binding and kickback. On a bench saw like the Craftsman 10321040, keeping the blade, fence, and riving knife/splitter working together is what keeps cuts accurate and safer.

Where is the reset button on a Craftsman table saw?
Most Craftsman table saws (including model 10321040) do not have a single, obvious “reset button” on the outside of the saw. The reset is typically part of the motor’s overload protection or the saw’s switch; you usually access it at the motor end-bell or by resetting the power switch after an overload trip.
What to check first (fast, safe resets)
- Turn the saw OFF, then unplug it.
- Let the motor cool 15 to 30 minutes (overload protectors often reset after cooling).
- Plug back in and try a normal start.
- If the saw uses a resettable switch (common on bench saws), press the switch’s reset or cycle it fully OFF then ON.
- If you tripped a breaker or GFCI, reset that device and retest.
Where the reset is commonly located on Craftsman bench saw motors
On many Craftsman bench-top designs, the overload reset is on or near the motor housing. A common layout is:
| Saw design | Typical reset location | What it looks like |
|---|---|---|
| Direct-drive bench saw | Motor end-bell (rear of motor) | Small button, cap, or access plug |
| Belt-drive bench saw | Motor body or starter/switch box | Button on a small module |
| No external reset | Internal thermal overload | Resets after cooling |
If you see two small plastic caps on the motor end, removing them may expose the overload mechanism on some motors. Pressing the reset (or the overload actuator) restores power after a trip.
If it keeps tripping after you reset it
- Dull blade or wrong blade for the cut (motor overload)
- Fence out of alignment causing binding
- Material pinching the blade (kickback risk)
- Extension cord too long or too light-gauge (voltage drop)
- Sawdust packed in the motor or switch
- Failing switch, cord, or motor windings
Why it matters
A tripping overload is a warning that the motor is drawing too much current. Resetting without fixing the cause can lead to repeated shutdowns and unsafe cutting conditions.
For electrical checks (switch, cord, continuity), use a meter and follow a proven test method like how to use a multimeter to test electrical parts video.
