Hi there guys, i just got a router and it came without a wrench, so i was wondering if all router nuts are the same size or do they vary, i don’t want to use a wrong size and ruin the nut, thanks !

The size varies. Sometimes standard, sometimes metric. Got a ruler?

What model router?

Go to your favorite pawn shop and dig through their bin of wrenches. Usually sell for $.50 to $1. And I agree with above post, that there are as many sizes of nut as there are brands of router.

You might need 2 wrenches. Some of them require one for the arbor as well.

Each brand seems to insist on having a different size. I find the quickest way is to buy an inexpensive (cheap)
caliper to measure the nut and then go the pawn shop route. I am lucky to have a good tool store here in
Missoula that actually stocks the wrenches for the routers they sell, so when I lost one, I simply drove over
and bought another. Do not ask how I “lost” the one.

And another thing about Tritons…I ordered a wrench for a Triton 3 1/4 HP and it did not fit my Triton 3 1/4 HP. I ordered the 2 1/4 HP wrench and it fit. I think Triton must have changed the collets they shipped with the later 3 1/4 models.

Double check to see if you can lock the shaft or if you need two wrenches – one to secure the shaft and one to loosen/tight the collet.

Edit: Is this it?

Yes, that’s the way to do it as even the cheap stamped wrenches that come with the router often don’t fit the collet nut worth a damn. I believe the nuts themselves are intentionally off-size as no wrenches under heaven seem to fit. I think it’s a common design feature to discourage mighty-mike-idiotts from using a long wrench and wrecking the threads and throwing router bits.

No Owners Manual? Those wrenches should have come with the Router!

You can be sure it is a metric size(s). My Bosch takes a 16 mm and a 24 mm. Do you have a digital caliper to measure it with.
