Impact driver

[1BURBAN]

Anyone know what the screwdriver you hit with a hammer is called. I have used the for opening the crank case on atv, and motorcycles. you hit the thing from the rear and it turns the force into a turning action at the other end of the driver. I need one to break loose some rusted interior fastners in my latest purchase. thanks

Impact Driver is the name given by any of the tool manufacturers I know. That is what we call it (Matco).
