Now this is much like the square drive that you guys will have in the US but it's better it's the head has a little bit more of a taper to it which grips the screw better I find a lot of times with square drive drivers and screws you'll put the screw on your drill turn around to put it wherever you're Metal Corner Brackets going to do it and screw falls off it doesn't just doesn't grip on there where is shaped a little differently and it kind of fits on there tighter and it doesn't fall off your driver easy so that that would be a  or square drive over here we've got can you see that we've got a  so it's kind of an X shaped Drive so that's that would be called the  Drive here we've got what I'd say is the most dangerous driving wall and should be outlawed in my opinion is the slotted Drive so you're going to be using a slotted screwdriver.

If you're actually trying to drive a wood screw in with a slotted screwdriver there is a very very good chance that your screwdriver is going to slip out of that little slot damage the work that you're you know the product you're trying to screw into or stab yourself in the finger so slotted screws I generally if I come across them in a project like I'm taking some of the parts I throw them away because I just won't use them and in fact, I had a hard time finding a screw to use as an example with a slotted head in it the other day when I was looking around because I didn't I just don't keep them so so slotted or square drive this is just another size of or square drive most of these heads will all come in our drivers will all come in three different sizes this one here Outdoor Screws being a number two or a number 8 pair sorry number two or a red is the most common size.

You're gonna use index screws and that sort of thing what do we got here so here we have a bit of a combination you could drive this with either a Phillips or a square drive with this particular one I think I skipped over this one didn't I yeah I did so this one's a Torx this is probably the best driver that you can get so this is a very positive lock when you put that driver in there there's no slipping no stripping these ones more and more screws are coming out with that so yeah the torque head style what do we got here again this is another combination one so it's a  and a  type head put together so this one here is a hex drive so you'd be using like a nut driver or that sort of thing to fit the head that's on there again that's actually a really good head as well but you typically won't see it on a smaller screw like this it'll typically be on some more of a speciality screw.
