Sometimes our site gets questions where the asker doesn't know what something is and provides a picture. As a site, we have come to the understanding that these types of questions are acceptable as long as the text of the question provides a description and detail.
My question is related. Once the answer is known (accepted or highly voted), should the title of the question be drastically changed to describe what was being asked about?
Pro
Changing the title makes it clear what the question was about for future visitors.
Con
Making a drastic change to the title can also make it seem like a completely different question. Someone just stumbling upon the question may be confused as to why a person had such a specific title (e.g. why did they need to ask?)
Some candidates (with possible new titles):
What is this screwdriver bit, and what is its purpose? (Is there a screwdriver bit for wingnuts?)
Name of spring actuated component (No idea...)
