"Hi! This is Drew Finn for Expert Village. We are going to talk about standard hand tools and how to use them. We are going to talk about how to use a wrench properly. First you got to do is choose a wrench the right size. These happen to be metric because I have a metric bolt to demonstrate with. On most wrenches, you've got the two sides. If the bolts are worn down at all, you never want to use this side because it is a smaller grip on the bolt itself so we want to use this side. So this is a light bolt and can be used to hold a planter inside the house or a similar one that you might have in a garage door bolt. You get the bolt on and turn it clockwise if you want to tighten it. Righty tighty is the thing or counter clockwise or lefty loosey. When the keys to the wrench, it's got to fit correctly. If you have a metric and this is a 10 millimeter metric and you try to use a 3/8 inch on it, it is going t6o slip and mess up the top of the bolt. So the basic thing is you got to fit the wrench correctly on the bolt and obviously turn it in the correct direction. "
