Mike,
I read one of your posts that was quoted in someone else's post, where you basically said that you were trying to use the right tool for the job. (see JarHead post above) You basically want a square socket for a square fastener. Okay. I still think an 8 point will work, but maybe you're trying to say that you'd like to use a vintage correct tool on the machine you're working on. I think I kind of understand where you're coming from. I like to tinker with old machines and cars. Somewhere along the line, I got this crazy idea in my head that it would make the tinkering even more enjoyable if I did it using vintage correct tools. (It gave me an excuse to buy more tools!!) As a result, I've been collecting older tools from the 1950s and 1960s to use when I'm working on vintage stuff. I've found that a 1/2" wrench from the 1960s doesn't turn a fastener any better than one from the 1980s or 1990s. Maybe it's just a purest mentality and I like collecting tools. Anyway, I still think an 8 point socket will work, but if you want a square socket, start hitting the flea markets and garage sales. You might just find a nice old set somewhere. Finally, tell us what type of machine you're working on.
