Which tool is used to notch and move stuck bolts with a flat tip?

• A. Sledgehammer
• B. Cold chisel
• C. Round punch
• D. Bar clamp

Answer: (B)

When a bolt is stuck, you need a tool that can create a small notch and give you a flat edge to pry against. A cold chisel fits that purpose because it’s a hardened steel tool with a flat edge that you can strike with a hammer to score or notch metal and then use the flat face as a lever to move the bolt. This controlled notching and prying helps break rust or seized material without mushrooming the bolt head or damaging nearby parts.

Using a sledgehammer would deliver large, uncontrolled blows and risk damaging threads or surrounding components. A round punch drives material through holes but doesn’t provide a flat edge for prying. A bar clamp holds parts together, not for cutting, notching, or prying. Safety note: wear eye protection and use the chisel with controlled strikes, backing up the work as needed.
