Could someone point me in the direction of the individual who decided that hex hardware on racing buggies was a good idea? I'm going to kill them.

Just why is hex hardware considered better? I have to buy a complete new toolbox, even though I have every size allen key in existence. The allens are just not good enough. Give me screws any day.

Now that I've finished moaning, the point is, when trying to take apart my (centre) diff with a precision allen key (and after trying the one that came with the kit), it still stripped the hex because neither was a perfect fit...so now I can't get the hex screw out, and therefore my centre diff is destined to have useless poxy grease in it the rest of it's days. I'm also worried of course, that I'll never be able to get it out now...

So, obviously, I'm off to buy a decent set of hex wrenches from the LHS tonight (more money!). Will I still be able to get it out do you think if I have a tool with the perfect hex fit? If not, anyone got any bright ideas, short of drilling it?
