Re: What are the name of the Allen wrenches with a hole in the center?
he's talking about the security version. the screws/bolsts have an allen head with a little cylender inside them so you can't fit a regular allen wrench inside. i dunno exactly what they're called, but I got a cheap bit set with most of those security type heads from my local Ace hardware, although I've never seen them there before or since. any good tool store should have them. I got my dad a set from a local place outside Chicago that just sells tools.
