A wrench works by applying torque on nuts and bolts. The repetitive up and down motion applied to the wrench gets the job done in about 30 seconds. Now, imagine a wrench that provides a continuous flow of motion when fastening things. Think about how much faster it would tighten nuts and bolts. If you are building a large structure, imagine the amount of time that such a wrench would save you. Think about all the things you can do with all that saved time. Now, you can stop imagining and get a real socket wrench.
The socket wrench has a racheting system that allows the tightening and loosening of nuts and bolts in one continuous motion. A removable socket is attached to the rachet of the socket wrench. The socket has a groove that can fit an entire nut or bolthead. Once the socket's groove covers a nut or a bolthead, users simply have to turn the handle of the socket wrench full circle. This lessens the amount of time needed to handle fasteners and requires users to require less effort.
The socket wrench comes with several removable sockets designed to fit the different sizes of fasteners and fittings. Users can switch sockets to conform to the size of a nut or bolt. Measuring sockets and impact sockets for other wrenches can also be fitted into the ratchet.
With its efficiency in managing nuts and bolts, wrench manufacturers have developed several types of the socket wrench. The six point socket wrench is designed to thoroughly fit into a hexagonal fastener, which is why it can turn damaged nuts and bolts. The deep socket wrench is used for bolts that are hard to reach. Impact wrenches are designed for high strength fasteners. The torque wrench gives the exact amount of force needed to tighten nuts and bolts. Apparently, there is probably a type of socket wrench for every fastening activity. With that being said, the socket wrench is arguably the most versatile member of the wrench family.
