Why the instrument is named Screw gauge?
The instrument is called a screw gauge, or more often a micrometer, because it uses a screw to amplify a very small movement so that it can easily be read. The heart of the screw gauge is a very accurately ground thread, usually of 0.5mm pitch, so that the axial movement of the screw corresponds to a much larger movement of a barrel which carries a scale. The instrument can be difficult to read because two readings have to be added, one measuring to 0.5mm the linear motion of the screw, and the other on the barrel giving the 1/100 ths. To some extent this instrument has been superseded by the electronic digital version, which does not incorporate a screw thread. A different gauge, called a thread gauge, comprises a set of metal blades with serrated edges which can be used to identify different screw threads by matching the right blade to the thread by trial and error.
