    What screws can fit through the holes on the wheels? The product page says it's .140" inches in diameter. Also, is there a mounting hub that I can use with this product and a 4mm diameter motor shaft? I just wanna stick the mounting hub on the motor shaft and have the mounting hub connected to the wheel.

Great wheel for the price

Very nice wheels, heavy duty as advertised. Good construction quality. The smooth rubber tread has good traction. Most retail vendors were out of stock on these wheels but Sparkfun had them in stock and for a good price.
