Which of the following is not used to measure the plain plug gauges if the tolerance less than 0.025 mm? Correct Answer Hand micrometer
If the tolerance on the plug gauge is less than 0.025 mm then, it is important to use more accurate measurement method. In such cases, bench micrometer or high magnification dial comparator or diameter measuring machine should be employed. In this case, hand micrometer can only measure over a limited range of size.
