Question 239General Subjects - QMED

The correct answer is C) Wire gauge. A wire gauge, also known as a sheet metal gauge or thickness gauge, is used to measure the thickness or gauge of a piece of sheet metal. This is the primary purpose of a wire gauge, which has a series of notches or slots that correspond to different standard thickness measurements. This makes it the appropriate tool for determining the gauge or thickness of a sheet metal sample. The other options are not the correct tools for this purpose. An inside micrometer (A) is used to measure the internal diameter of a hole or opening. A circular mil (B) is a unit of area, not a tool for measuring thickness. A gauge calibrator (D) is used to calibrate and verify the accuracy of other measuring instruments, not to directly measure sheet metal thickness.
