Question:
A ratchet screw in a micrometer is provided to
A ratchet screw in a micrometer is provided to
Show Hint
The ratchet mechanism in a micrometer prevents measurement errors caused by variations in applied pressure ensuring repeatable results
Updated On: Jan 17, 2026
- allow zero adjustment
- prevent wearing of screw thread
- lock the required measurement
- maintain constant pressure on the job specimen
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
A ratchet screw in a micrometer is used to apply a constant pressure on the job specimen ensuring that the measurement is consistent and accurate regardless of the user’s hand pressure
