Are these geared motors holes

the same size as these

it may seem like an odd question, but I bought two of those right shaft geared motors and I have yet to find an axel that fits inside of it (no i didnt buy the wheels that came with it)
In other words would those sparkfun wheels be able to mount on the hobby engineering motors(same size?)
