What tool is used to tighten nuts, bolts, and fasteners to a specific tolerance?

• A. Ratcheting wrench
• B. Pipe wrench
• C. Torque wrench
• D. Adjustable wrench

Answer: (C)

A torque wrench is a specialized tool that measures and applies a specific amount of torque to a fastener such as a nut or bolt. This tool is essential because it ensures that fasteners are tightened within defined tolerances, which is critical in many applications to avoid over-tightening or under-tightening. Over-tightening can lead to damage, failure, or warping of components, while under-tightening can result in loose connections that can compromise safety and integrity. Using a torque wrench allows the operator to be precise in their work, following specifications that are often provided in equipment manuals or engineering drawings. The design of the torque wrench allows for measurement and adjustment, incorporating mechanisms that either click or indicate when the desired torque level has been reached. This makes it an invaluable tool for maintaining the safety and reliability of mechanical structures and systems. In contrast, while tools like ratcheting wrenches, pipe wrenches, and adjustable wrenches are useful for gripping and turning fasteners, they do not provide a means to measure or control the torque being applied, making them unsuitable for tasks requiring specific torque tolerances.
