What is the primary function of a hinged handle on a wrench?

The primary function of a hinged handle on a wrench is to offer flexibility in tight spaces. Hinged handles allow the wrench to be maneuvered in areas where a straight tool would be difficult or impossible to use. This design enables the user to apply torque in tricky positions, making it particularly useful in confined spaces commonly encountered in automotive and aircraft maintenance. The hinge mechanism allows for a greater range of motion, facilitating access to fasteners located in areas that would otherwise be challenging to reach.

While providing rotation and leverage are important aspects of wrench design, a hinged handle specifically enhances accessibility rather than simply improving the rotation or increasing the force applied. The options related to serving as a cutting tool do not apply in this context, as wrenches are primarily designed for turning nuts and bolts rather than cutting.
