"The next thing that we're going to be discussing is about hand tools are wrenches. Wrenches come in a variety of sizes and shapes. You have open ended and closed end wrenches which are commonly called boxed end wrenches. Wrenches come in two styles, metric and US., metrics are ran from the smallest number is 5.5 and up until eighteen to nineteen and some other measurements. The other wrenches come from three eighths and they do range smaller but from three eighths to thirteen sixteenths, most of the common knowledge screws are half inch, five eighths, and nine sixteenths. Here we have a five eighths wrench and here we have a fifteen millimeter wrench. As you can see, they are both similar in sizes, one is just a degree smaller than the other as far as for the metric.
