A four-piece socket adaptor set in high-strength chrome vanadium steel that improves compatibility between common drive sizes, so you can switch between ratchets, extensions and sockets without swapping tools. A spring-loaded ball detent holds sockets securely.

The polished, corrosion-resistant finish withstands high torque and heavy use, and the compact, lightweight set stores neatly in a toolbox or bag ideal for on-the-go repairs.
