Which tool type is primarily used for holding and turning objects?

Wrenches are specifically designed to grip and turn fasteners, such as nuts and bolts. Their primary function is to provide a mechanical advantage when applying torque to an object, allowing the user to tighten or loosen components securely. The various designs of wrenches, including box-end, open-end, and adjustable types, cater to different shapes and sizes of fasteners, enabling precise handling and effective operation.

While pliers are also used to grip and turn objects, they serve a broader purpose, including cutting and bending, which is secondary to their function. Drills and saws are tools primarily used for creating holes or cutting materials rather than turning or holding. Therefore, wrenches stand out as the tools most directly associated with the task of holding and turning objects.
