What is the screw thread & size, and length for attaching the RB-Nex-17 hubs to the RB-Nex-96 wheels?
Hello @becksteadja and welcome to the RobotShop forum,
The holes on the hub aren’t threaded, the diameter is 5.2mm and the length for attaching to a wheel should be longer than 10mm (<50mm). Also, note that the wheels set comes with a longer set of screws to mount on a hub.
Oh, and if you ever need help matching wheels and hubs this guide should help:
