Adapters, extensions, and universal joints are designed for sockets and ratchet wrenches to reach bolts and nuts in tight or difficult-to-access spaces. Adapters connect sockets to different drives, extensions increase reach, and universal joints provide flexibility for angled work. These accessories improve efficiency, allow access to hard-to-reach areas, and ensure precise torque application. High-quality adapters and joints are suitable for both professional mechanics and DIY enthusiasts.
