The nub is a series of hubs intended to connect motion components to spinning shafts, like sprockets gears, pulleys and wheels. It supports the output shaft of the AndyMark NeveRest motors as well as the other motors on the market. It supports the AndyMark 6mm D shafts for robust motion systems and impeccable torque transfer. The four mounting holes on these nubs are sized at 0.128" diameter, with the intention of accepting a #6-32 threaded screw. They are not tapped, but can be tapped by most machine screws due to this diameter.
