A socket wrench is one of the most basic tools in any tool box. They are used to tighten nuts and bolts that make connections between two pieces of wood or metal. A socket wrench is different from a crescent wrench as you do not have to remove the wrench from the bolt to turn it.
Socket wrenches work on a ratchet system that allows you to tighten, or loosen, the bolt, and then move it in the other direction without interfering with the bolt. They use a series of different sized sockets that can be standard, or metric, that can be used on a wide variety of different nuts and bolts.
Select Right Size Socket
In order to use your socket wrench efficiently you need to use the right size socket. Using a socket that is slightly larger than the right socket will lead to slips of the wrench or the bolt being stripped.
You are either going to be tightening the bolt or loosening it. By using the small lever on the backside of the socket wrench you can select which direction you want the ratchet set.
A great thing about socket wrenches is their reach. If you can not quite reach the bolt, you can use an extension bar to attach the socket to. This will not only give you extra reach, but will also give you leverage with a stubborn bolt.
