These mirror-polished premium chrome vanadium spark plug sockets are strong as well as beautiful.

These sockets offer more than just a stylish exterior though. The sleek chrome finish is enhanced with an easy to read size marking that is forged into the metal. 

Because it's forged into the socket wall, the marking won't rust or wear off - ever.

Beauty is more than skin-deep though.

Inside Powerbuilt sockets you'll find precision chamfered hex faces that make it easier to guide them onto fasteners.

And the exclusive Z-Drive 6 point hex pattern grabs and turn the flat surfaces of spark plugs to reduce round-off and slipping. 

Dependable Powerbuilt sockets meet or exceed ANSI standards and have a lifetime warranty, all at affordable prices.
