 What the heck is an Allen wrench? Hola woodworkers, Paul Carlson here, small workshop guy. Allen wrenches, they're also known as hex keys, ATX keys, comes from the word hexagon because they're in the shape of an hexagon on the end of them and that fixed into a socket that's of the same shape. The problem is you have to match the size to the socket. Therefore, you end up over time having a whole drawer full of these things laying around loose. Take it out there, you use it, you set it down, you forgot where you got it, it never gets back in there. Here's two incomplete sets and again this is typical. Got them all over the place, never can find the one that you want. So what have I found in my workshop? Well, I've found that I better get something that I can't take apart. Therefore I can't lose the individual pieces. So I found these from DeWalt. You can get them both in SAE or Imperial or you can get them in millimeters. And they're in a nice case that you can handle. You can hold it in your apron, a little heavy, but depending on how many things you've got in your apron already. And they've got a pretty good size. In some cases you need something bigger, so maybe you have a handful of larger ones around. But there are eight different ones in here. Three bigger ones on this side and then five smaller ones on this side. And frankly, I hardly ever find a situation where something out of one of these two sets will not work for what I'm trying to do. Again, they're slightly different sizes because they're in thousands of an inch and in millimeters. Anyway, I like that. I like it because I don't lose them. And so I just put all the rest of these in a sack somewhere and forget about them. Everybody will get rid of them when the old coot dies. And then my son, Will and Herrick, a nice set of Allen wrenches, hex keys, Allen keys. They were patented in 1909 by W.G. Allen and they were originally produced by the Allen Manufacturing Company here in the U.S. You can't stop the waves, but you can learn to surf. Smaller Shab Guy, signing off.
