Designed to adapt drills and impact wrenches to accept socket inserts. The PRO Socket Adapter provides a quick solution when you need to use impact wrench socket inserts. It features a square drive with a ¼-inch hex shank, allowing you to connect sockets to your drill and impact wrench. With the PRO Socket Adapter, you can tighten and remove fasteners such as screws and nuts using your drill or impact wrench. It has a square drive that is compatible with square impact sockets. The square drive with ball or pin connection makes it easy to attach and detach socket inserts. Suitable for applications under 80 Nm. For heavier tasks, such as changing tires, we recommend using the sockets directly with an impact wrench. Impact-resistant ¼-inch hex shank for use with impact wrenches and drills.
