Measure Wheel Hex Size

[KalEl63 695]

I was measuring my wheel hex’s on the CR-01 to get clap on ones and I was getting around 5.80mm so is that actually a 6mm hex?

I would say yes,  nominally 6mm. The across faces measure is usually the 1st size listed then the width.

It can be another pit of oblivion, a bit like wheels and tyres, when there are no absolute measurements given by some sellers.

I bought some aluminium hexes a little while back and had to mill 1mm of the face to get the fit I was after. Ok if you have a milling machine, but a bit of a bind if not.

What size is the hex on the wheel?

The hexes size is 12mm, the thickness is approx 5-6mm for the standard Tamiya.
