Which tool is designed for gripping pipes with an adjustable jaw?

• A. Box End Wrench
• B. Combination Wrench
• C. Pipe Wrench
• D. Needle Nose Pliers

Answer: (C)

When you need to grip pipes of different sizes with solid leverage, you want a tool whose jaws can adjust to fit the pipe and bite into it for a secure hold. A pipe wrench delivers that exactly: it uses a movable jaw operated by a worm gear, so turning the handle tightens the lower jaw around the pipe, and the serrated teeth grip the surface to prevent slipping. The long handle provides the torque needed to turn fittings firmly without slippage. The other tools aren’t suited for this task: box end and combination wrenches are for hex nuts and bolts and have smooth or fixed jaws, not adjustable jaw grips for pipes; needle-nose pliers are for small, delicate objects and lack the torque and pipe-gripping ability.
