Question: 1 / 400

Which tool is essential for tightening or loosening hexagonal nuts and bolts?

Phillips screwdriver

Adjustable wrench

The adjustable wrench is essential for tightening or loosening hexagonal nuts and bolts due to its design that accommodates a wide range of sizes, making it versatile for various applications. Its jaws can be adjusted to fit around the flat sides of hexagonal fasteners, allowing for a secure grip while applying torque. This capability enables the user to effectively turn and secure nuts and bolts without slipping off, which is crucial for maintaining tight connections in mechanical systems.

In contrast, the other tools listed, like the Phillips screwdriver and flathead screwdriver, are designed for driving screws rather than gripping and turning nuts or bolts. Pliers have limited grip on hexagonal shapes, making them less effective for this specific task compared to the adjustable wrench. The unique functionality of the adjustable wrench makes it the most suitable choice for the job.
