VersaPlanetary 1/2" Hex Output Shaft Kit Hole Size

[xForceDee]

I am looking at using the a versa planetary to drive some wheels. I plan to attach them via this hex shaft (http://www.vexrobotics.com/217-2897.html). I want to model this setup in CAD and my problem is I cannot find the information about the diameter and pitch of the the threaded hole at the edge of the shaft. I would like to use a bolt and some washers to retain the wheel. If anyone has this information that would be awesome! Thanks

I'm not sure but I would assume it is a 1/4-20 tapped hole.

I'm sure someone else will chime in with the right answer.

Yep, 1/4-20. We will have layout drawings soon with all pertinent layout information.
