Could you explain further on this? I'm not sure why this is.
I cant give you the exact science on it, but I'm sure it has something to do with the way the torque is applied to the bolt and the surface area. Try taking one off for the first time using just the 1/2 extension insert. It's not gonna happen.
I actually tested it on my girlfriends car recently with a Milwaukee 1400 ft/lb off torque impact just to see if it could do it. It actually cracked the head of the bolt before it even budged. I put a socket over it and it zipped right off.
Given my experiences with trying to get those bolts off with the extension only, and the fact the only time I ever had one back out was when I torqued it with the extension only, I'm sure there is a reason.
