a #10 setscrew NORMALLY uses the 5/32"
(which I *thought* was the VEX screw wrench, isn't it?)

I'd be REALLY surprised if you'd need two different wrenches.
(Maybe they obtained a non-standard 8-32 screw, to keep it compatible...)

Unfortunately, I don't have a compatible CAD available right now to view those docs.

OOC, Can you please take another quick peek at the CAD again, and see which WRENCH the setscrew uses? Is it 5/32", or another size?
(To measure an Allen Wrench's size, simply measure between opposite flats.)

Thanks again!

The cad shows it as 5/64. I know that the wrench for the setscrew is the same wrench as for the 6-32 motor mount screws, which is indeed smaller than the standard 8-32 vex screws.

The setscrew on a VEX lock collar DEFINITELY is 8-32, and the allen wrench size is 5/64". Trust me on this. I've purchased hundreds for our VEX teams.

As an extension, you shouldn't even worry about the set screw if you are short on time. Any normal 8-32 screw from the vex kit will work, and you won't have to worry about the 5/64" allen wrench either.

You might want to try a hobby store. They'll probably be called "wheel collars" found usually with the r/c airplane stuff. They use them to attach wheels onto planes which freespin.

Good luck!

I also have bought them in small quantity from our local Ace Hardware. The cheapest place I've found is the VEX Website -- cheaper than McMaster-Carr.

Yes, making them and McM-C are both more expensive that buying them from VEX. Even with the one day overnight they will be cheaper to buy from them.
