Basically, a socket wrench is simply a handle with a 90-degree crank. It usually comes with several differently-sized screw sockets, although those are generally interchangeable so that you do not necessarily have to purchase a whole new set of them at once anyway. To use a socket wrench, first you will put the required socket onto the crank and then apply enough torque to make the handle to rotate freely. Then, release the grip and pull back on the handle to loosen the nut.
If you do not have any socket wrench in your tool box, then you should consider getting a new one. The reason why you need a new one is because old sockets can be stripped or damaged easily. Another reason is that different manufacturers designed their own ratchets differently, leading to different tightening and loosening power. This can mean that you might need to go back to the shop to get the right one. Fortunately, there are many online resources that can help you find a high-quality replacement or a compatible one for your needs.
One of the most important things you need to know before buying a socket wrench set is how the handle works. There are two types of handles: standard and ratchet style only natural anchors like. Standard handles will screw on to the socket, while the ratchet style will have a clip or hook on the handle. With a standard grip, you will need a pair of pliers and two sizes of nuts. However, with the ratchet style you will need only two sets of nuts and a single pair of pliers.
Another important factor when you are choosing a socket wrench set is the size of the socket wrench itself. Some sizes are smaller than others, so it all depends on the job you need done. Thinner sockets are usually smaller than standard ones, so you will need a smaller pair of pliers in order to accomplish the task. The best thing to do is put the job you are doing on paper or a computer so you know roughly how much torque you will need. This will also help you narrow down the selection of sockets to purchase.
There are two basic styles of socket wrench – the full set and the trigger-operated version. The full set consists of a handle, body, spring and nut assembly. This is probably the best style if you want to purchase a single tool that has all the functionality you need. The ratcheting wrench type will allow you to choose one size of socket, switch the spring and tighten or loosen the nut, while the electronic version works by having a small button that switches the action of the nut and a small clip that attaches to the handle.
The electronic socket wrench offers some advantages over the older model that uses a push-type action: it is easier to use, and it is less likely to be damaged if you accidentally hit the nut or the body of the tool. It also works better with insulated tools because the spring can run freely without the danger of overheating. The new crescent wrench is also easier to use because the notch on the side of the tool allows you to grasp the open end with your fingertips. Finally, there is a convenience feature available on crescent wrenches that allow you to open a can or a bottle without having to remove the cap.
