What type of tool is used to provide torque effectively?

• A. A screwdriver
• B. A wrench
• C. A hammer
• D. A saw

Answer: (B)

A wrench is specifically designed to apply torque to fasteners, such as nuts and bolts. Its shape allows for a firm grip around the head of the fastener, enabling the user to turn it with significant force. The leverage provided by the length of the wrench's handle also enhances its ability to tighten or loosen fasteners effectively, making it particularly useful in mechanical and construction applications. In contrast, while a screwdriver can provide torque, it is primarily designed for use with screws and does not offer the same level of versatility in applying torque to various types of fasteners. A hammer, on the other hand, is used for striking, driving, or breaking objects, rather than applying torque. Similarly, a saw is a cutting tool that does not engage in torque application at all. Therefore, among the choices given, a wrench is the most effective tool for providing torque.
