A specific type of hand tool facilitates the tightening and loosening of nuts and bolts. This collection typically includes a variety of sockets in different sizes, designed to fit a range of fasteners. The “drive” size refers to the square recess in each socket, which corresponds to the matching square drive on the ratchet or other driving tool. A common configuration includes both metric and SAE (Society of Automotive Engineers) sizes to accommodate various applications. Often, this set includes additional components like extensions, universal joints, and adapters for increased versatility.
This tool assortment is essential for mechanics, automotive enthusiasts, and anyone working with machinery or equipment. The range of socket sizes ensures compatibility with a wide array of fastener heads. The specific drive size offers a balance of strength and accessibility, making it suitable for many automotive and general mechanical tasks. Historically, the development of standardized drive systems revolutionized mechanical work, allowing for interchangeable sockets and more efficient repairs. This standardization remains a key aspect of modern tool design.
