Which tool is specifically designed to grip and turn nuts and bolts?

• A. Stillson wrench
• B. Torque wrench
• C. Pipe wrench
• D. Flat-head screwdriver

Answer: (A)

The Stillson wrench is specifically designed for gripping and turning nuts and bolts due to its adjustable jaw and serrated teeth that provide a strong grip on various sizes of fasteners. This tool allows for significant leverage and is particularly effective for applying torque when loosening or tightening fittings, especially in plumbing and mechanical applications. Its unique design enables it to accommodate a range of nut and bolt sizes, making it a versatile tool in many trades. In contrast, while a torque wrench is crucial for applying a specified amount of torque to a fastener, its primary function is not to grip or turn but to measure the torque being applied. A pipe wrench, designed predominantly for gripping round or tubular objects like pipes, does not perform as effectively on flat-sided nuts and bolts as the Stillson wrench does. A flat-head screwdriver is intended for driving screws, not for gripping or turning nuts and bolts, further emphasizing why the Stillson wrench is the most suitable tool for this action.
