Socket Extensions

Attach these extensions to your socket for a longer reach. Use with hand-drive tools only.

Chrome-Plated Steel—Chrome-plated extensions have a smooth, shiny surface that resists corrosion and is easy to clean.

Black-Oxide Steel—Black-oxide extensions aren’t as smooth as chrome-plated extensions, so they’re easier to grip when dirty or wet. Oil them periodically to maintain their corrosion resistance.

Strong-Hold Impact Socket Extensions

Lock your socket into the extension to prevent accidental disengagement. Locked in place by a ball that retracts when the collar is pulled (also called positive locking), these sockets hold more securely than our standard extensions. These extensions are thicker than standard extensions, and also have enough give to flex under high force without breaking. This makes them a good choice for use with impact tools.

Strong-Hold Impact Socket Extension Sets

Also known as positive-locking extensions, these extensions hold sockets in place with a ball that only retracts when you pull the collar down. Designed to prevent accidental detachment, they lock to your socket more securely than other extensions. They’re thicker and less brittle than manual extensions, so they withstand the high torque and force of impact tools. They flex slightly when force is applied, so they’re less likely to break. Each set includes three common extension lengths to tackle a variety of jobs.
