A set of sockets designed for use with ratchets and other turning tools typically includes a range of sizes, both shallow and deep, to accommodate various fastener head depths. The tools are engineered for use with fasteners utilizing the metric system and are designated with a specific drive size, influencing the amount of torque that can be applied. A common configuration includes both 3/8-inch and 1/4-inch square drives to handle a wider spectrum of fastening tasks.
The availability of two distinct drive sizes within a single kit provides versatility for tackling diverse projects. Smaller drive tools offer precision and control for delicate fasteners, while larger drive tools deliver the necessary torque for heavier-duty applications. This combination enhances efficiency by eliminating the need for multiple socket sets. The standardization afforded by the metric system ensures compatibility with a broad range of internationally manufactured equipment and components. Historically, the development and adoption of such standardized toolsets have significantly improved mechanical work efficiency and reliability.
