What does a Universal Joint allow you to do with nuts/bolts?

A Universal Joint, often used in conjunction with sockets and ratchets, is designed to allow for flexible movement in multiple directions. When attaching or loosening nuts and bolts, the Universal Joint enables the user to turn the handle at an angle rather than straight on. This is particularly useful in confined spaces where direct access to the fastener is obstructed.

By allowing the handle to be held at an angle, the Universal Joint maintains the ability to transmit torque even when alignment between the socket and fastener is not perfect. This feature enhances accessibility and ease of use, making it significantly easier to work on various types of machinery or equipment where a straight line of access is not feasible.

The other options do not accurately encapsulate the primary function of a Universal Joint regarding nuts and bolts.
