70% to passA thread chaser is a hand tool that should only be used for _______________.
Aenlarging existing threads
Bstraightening tapered threads
Crestoring damaged threads
Dcutting original threads
AI Explanation
The correct answer is C) restoring damaged threads. A thread chaser is a hand tool used to restore or repair damaged threads on nuts, bolts, and other threaded fasteners. It is specifically designed to remove minor defects or burrs on the threads without removing a significant amount of material. This helps to preserve the original thread size and profile. The other options are incorrect because: A) Enlarging existing threads would require a different tool, such as a tap or die. B) Straightening tapered threads is not the purpose of a thread chaser. D) Cutting original threads is also not the intended use, as that would require a tap or die set.
