The socket used in many of the tools in the evercraft tool set is 3/4″ drive and a bit hard to find online. However, you can buy it online for a fraction of the price. It is important to have this kind of socket because it will allow you to use the wrench on most standard screwdrivers. It will also give you an easy way to drive screws and other nuts in the screwdriver. This is an important tool for most DIYers and will make your work easier.
