Kerry mentioned a magical tool... the hand impact driver... motorcycle mechanics could not live without one...
This is not the same thing as an air impact driver...
The magical part of it is that it puts force forward into the nut/bolt/hex at the same time it puts turning force on it... a regular air or electric impact only puts force in the turning direction...
This means it can even bring out stuck Phillips head screws... that are partly messed up...
This is one of the greatest " larger hammer"" "next level" tools anyone can have in their toolbox....and they are relatively cheap...

One caution though... be sure you know how to set it so that it turns the proper direction when you hit it... otherwise you can really tighten up that bolt....
