Just buy this, I will leave it at that. I have this for both screws and sockets, i use to snap constantly because we are in rust belts. these tools i have greater then 80% success rate walking the bolts out. as long as you have the clearance to get it in there.
this sends a impact down the entire screw and bolt, not just the head like a normal impact
