How wide are the holes on plates and other metal?

Yeah, the title.

Checked with calipers, 4.7mm.

Most precise would be in the CAD, might check later if no one else does in the meant time

if you go to VEX Robotics and look up whatever part you’re interested in, on the “docs and downloads” tab you can find specifications for each part. Most parts have both a CAD file, as well as a .pdf file of the print with specifications listed.

As a general rule, the centers of holes are spaced 0.5" from each other.
This is the same for all parts.
I know this from when I made my SOLIDWORKS library and also it is stated somewhere on

Edit I can’t read. Holes are 0.182" wide
