The Abrams shown has 2x18mm screws and lock nuts. They can be

I have used slightly smaller and slightly larger diameter screws/nuts when building sets of these arms and wheels for others. I would recommend starting off with 2mm and determining the need for change from there, but whatever the size keep all the screws and nuts the same measurements.
