Question 164General Subjects - QMED

The correct answer is C) micrometer. A micrometer is the appropriate tool to use for measuring the thickness of thin shim stock because it is designed to provide precise measurements of small thicknesses, typically in increments of 0.001 inches or 0.01 millimeters. This level of precision is necessary when checking the thickness of shim stock, which is used to make bearing shims, in order to ensure a proper fit and function. The other options are not as suitable for this task. A machinist's rule (A) would not provide the necessary precision, a feeler gage (B) is typically used for measuring gaps rather than thicknesses, and a depth gage (D) is more appropriate for measuring the depth of a hole or recess, not the thickness of a material.
