Bolts are rarely out in the open; they are buried deep behind intake manifolds, inside wheel wells, or under dashboards. A socket extension bridges the gap, extending your ratchet's reach by anywhere from 1 inch to 3 feet. They are made of chrome-plated steel with a square drive end on one side and a square socket receiver on the other. For hard-to-reach angles, wobble extensions allow the socket to tilt slightly, helping you spin fasteners that aren't perfectly aligned with the tool.

Frequently Asked Questions
It is an extension with a slightly curved drive end that lets the socket pivot up to 15 degrees, allowing you to turn bolts at a slight angle.
Yes, but the connection points will introduce play and flex, reducing the torque transmitted to the bolt. Use a single long extension if possible.
No. Standard extensions are brittle and can shatter under impact force. Always use thick, black-oxide coated impact-rated extensions for power tools.
