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.
