Micrometer Screw Gauge: Parts of a Micrometer Screw & Functions

Screw gauge, also known as micrometer screw gauge, is a device used for precision measurements. Micrometer screw gauge is used for measuring extremely small dimensions which the vernier caliper cannot measure. Using "screw" principle, a micrometer screw gauge amplifies smaller distances into large measurable distances. Find out about the different parts of micrometer screw gauge, along with its construction and principle in the article inside. Thus the main parts of a micrometer screw gauge are: Frame, Anvil, Spindle, Sleeve, Thimble, Ratchet, Screw, Lock
