Razor Metro Axle Thread Size

[chuckwalla]

I'm pondering installing these quick release adaptors but I can't find what the axle diameter and thread pitch is?

I contacted Razor but no go and I've never seen replacements for sale. Does any one know if they're 3/8-24, 3/8-26 or maybe M10-1?

Thanks!

There is no info of that in their page.
it look standard 10mm wide diameter axle. but it would be 12mm or 14mm height diameter
