A collection of sockets and related tools, typically including a ratchet handle, extensions, and often a universal joint, designed to engage fasteners with a square recess. A common example includes a set with both metric and SAE (Society of Automotive Engineers) sizes, providing versatility for various applications.
Such toolkits are indispensable for mechanics, technicians, and even DIY enthusiasts. They provide the necessary leverage and grip to tighten or loosen nuts and bolts efficiently and safely, preventing damage to fasteners and surrounding materials. The standardized square drive sizes ensure compatibility across a wide range of tools and accessories. Over time, these sets have evolved to include features like quick-release mechanisms and improved materials for greater durability and user convenience.
