 An overview about wood screws. Hola woodworkers, Paul Carlson here, a small workshop guy. If you notice a bad left eye, I got a shot at it in the doctor head and blood vessel, so it's in bad shape right now. To start our discussion on wood screws, let's make our Canadians friends happy and talk about the Robertson first. The Robertson, you would be familiar with the Kreg pocket hole jigs. That has a Robertson square head on it. So it's, you have to have a square bit obviously. An advantage of them are that they fit very nicely on there. They, for whatever reason that I don't understand, they don't drop off. Same thing, sort of true for another one I'm going to talk about. So that's the Robertson square head. That's primarily what everybody in Canada uses. Now in the U.S., our most common is the Phillips. But the Phillips got some downsides. The Phillips is just a little crosshatch. And it's okay but it tends to slip. An improvement over that is the Torx, T-O-R-X. And that's a little star pattern. And those come with bits in the boxes so that you have the right size star pattern bit to go with your screws. Okay, so that's the three primary types. They are, screws are either designed to be, to stop at the top of the workpiece and not go down into it. Or they are designed to actually embed themselves into the workpiece and be flat with the surface. Many of the better ones have a little kind of a teeth arrangement on the underside of the head in order to allow it to drive further down. Disadvantages to that is if you keep using your impact driver on it, it'll keep driving down. So be careful when you do it down. The screws can either come fully threaded where the threads go all the way from top to bottom. Or they can come where they're just partially threaded. Usually about two thirds threaded and then a third smooth. Different reasons for that. I'll give you a link to a video down below describing the thought process there. My favorites are SPAX and GRK. They're a little higher quality. They cost more but they're worth it, believe me. And that's kind of an overview of screws. Very basic. Small workshop guy, signing off.
