No, expando drums have telescoping bushings to adapt to any shaft size. You will need big flat washers or flange washers on each side and a nut on the shaft end to tighten down. If your shaft isn't threaded you can buy shaft adapters that slide over the shaft and have set screws and flanges and nuts to hold wheels and drums. You can also have the shaft threaded and stack your wheels and drums with spacers in between and tighten them all down with a nut on the shaft end. Remember that the left side has to be left hand thread and the right ride right hand. Shaft adapters are available from Covington Engineering.
