What type of wrench would you use if you need to tighten a nut in a confined space?

An offset wrench is particularly advantageous for tightening nuts in confined spaces due to its design, which allows for easier access to fasteners that are difficult to reach with standard wrenches. The handle is angled away from the jaws, creating a profile that can fit into tight areas. This feature is extremely useful when dealing with nuts that are situated closely against other surfaces, where a straight wrench would be impractical.

Socket wrenches, while versatile and effective for many situations, require space to accommodate the socket and handle. Ratcheting wrenches also need a certain amount of clearance to pivot, making them less suitable for very cramped quarters. Box-end wrenches can be effective, but they typically do not have the offset advantage that allows for better maneuverability in tight spots. Therefore, when the working environment is restricted, the offset wrench remains the best choice for tightening nuts effectively.
