"Hi! I'm Drew Finn here for Expert Village and we are going to talk about standard hand tools and how to use them. Now we've got some manual screwdrivers both with a Phillips and for the slided screw and I am going to demonstrate how those are used. Now what we have to do obviously first is know what kind of screw we are driving. Whether you have a Phillips or one with a slot in it. This one happens to be a Phillips. Now one of them ore important things is to choose the right size screwdriver for the Phillips. For instance if we used this very small Phillips in here it doesn't quite fill up, it's much more likely to slip out and ruin the screw. So what we want to do is size, choose the right screwdriver for the screw. Now this one fits like perfect. So this is the one we want to use for this particular screw. Actually it holds on there just like that. That is how good a fit we have whereas with the little guy that is not going to stay on there very well at all, just falls off. So we just take this, put the screwdriver on and then you probably want to hold the screwdriver in this area to keep it straight when you are screwing in. You got to apply some axial force to it to actually get it in. So on any of these screws if you can drill a pilot hole first it helps. It depends on what you are going in to. If it skips, pops out of the head and starts breaking metal off here, it would be wisest to back it off, throw the screw out and start with a new screw. Another little trick you might have if you have trouble driving it in, is put a little soap on here, liquid soap on the threads first and they will drive down much easier."
