A small-sized tool, typically made of hardened steel, connects a ratchet or other turning tool to a socket. This allows for access to fasteners in confined spaces or at awkward angles. A common example is its use with a socket wrench to tighten or loosen bolts in automotive repair.
This compact tool offers significant mechanical advantages. It enhances torque application, making tasks easier and more efficient. Furthermore, its relatively small size allows access to otherwise unreachable areas, proving indispensable in various mechanical and engineering applications. Its development evolved from the need for more versatile and adaptable tools in increasingly complex machinery.
