A socket is a tool that attaches to a socket wrench, ratchet spanner, torque wrench or another turning tool in order to tighten or loosen a fastener such as a nut or a bolt by turning it. Made from high-quality materials, such as forged metals, for strength and durability, these tools are designed to withstand high torque as they help to loosen or fasten nuts, bolts and other fasteners.
Socket sets have an extensive range of all shapes and sizes with a square drive metric connection. The more pieces within the socket set, the more versatility this gives you to ensure you have the right socket for the job in hand. Socket sizes can come in a variety of sizes, from metric to imperial, ensuring you have the correct size for any job you require. Please see our socket sets guide for more information.
Our range of socket sets features products from some of the most popular brands in the industry, including Bahco, Facom, GearWrench, RS PRO, Stanley, Teng Tools and Wera.
Sometimes socket sets will have a combination of socket types, whereas other may be focused on providing a range of sizes in one type. Sockets can be metric, measured in mm, or imperial, measured in inches, or they can come in Torx sizes, which are displayed as TX followed by a number.
Mechanics often use sockets in commercial or home garages. They use the sockets along with a turning tool to loosen or tighten nuts and bolts on cars, truck, buses and other vehicles. Smaller sockets can be used with a spinner handle or smaller ratchet for use on hard drives or computers for example.
