What size is it? I'm dealing with a huge backbow problem, and I don't have L shaped hex keys (or whatever) so I'll go buy one, just want to konw what size it should be.. yep.

Thanks in advance!

I have a very hard time just buying 1 allen wrench unless it is off the Snap On truck. Get a whole set for like $10 then you are set for lots of stuff. I have good luck with ball end ones that can be used at a angle. Only time those are not any good is when stuff is real tight.
What the hell!!!
