Final answer:
If the threads of a fastener are not too badly damaged, a thread file can be used to clean them up. A thread file can be used to clean up slightly damaged threads on a fastener, making option A the correct answer. It's a useful tool for minor repairs, avoiding the need for immediate replacement of the fastener if the damage is not severe. option C) Both A and B the correct answer.
Step-by-step explanation:
If the threads of a fastener are not too badly damaged, such as when the outer thread is slightly damaged from being started crooked (cross-threaded), then a thread file can be used to clean them up.
A thread file is a specialized tool used for repairing damaged or cross-threaded threads. It has a series of cutting teeth that can reshape the damaged threads, allowing the fastener to properly engage.
By using a thread file, the student can salvage the fastener and avoid the need for a new bolt or nut, making option C) Both A and B the correct answer.

If the threads of a fastener are not too badly damaged, such as when the outer thread is slightly damaged from being started crooked (cross-threaded), then a thread file can be used to clean them up. Option A is correct in this case. A thread file is a tool specifically designed to repair minor thread damage. It allows you to restore the threads without the need for replacing the entire bolt or nut, provided that the threads are not too severely damaged. If a thread file is not sufficient to repair the threads, or if the damage is extensive, then you might need to replace the bolt or nut. However, if the damage is slight, using a thread file can be a cost-effective and simple solution.
