Gives that extra force when needed.
There are occasions where you need extra torque to get a stubborn born loose and you are unable to get any power tool in place to help. That is where this things shines. I recently had rotator cuff surgery and cannot use my left arm currently to provide any torque and this part fits into a wrench with another breaker bar attached to it for example and has worked like a champ.

More ‘umph'
Strong and easy to use. If you need that ‘extra' torque this is the one to use.
