A micrometer screw gauge is used for measuring dimensions smaller than those measured by the vernier calipers. A differential screw is a mechanism used for making small, precise adjustments to the spacing between two objects (such as in focusing a microscope, moving the anvils of a micrometer, or positioning optics).A differential screw uses a spindle with two screw threads of differing leads (in case of a single lead equalto the thread pitch), and possibly opposite handedness, on which two nuts move. When you have to open or close the micrometer a, When storing the micrometer always leave some, Learn how to hold it in your hand so it is. Provided with a 60 degree V-anvil and conical spindle for easily measuring pitch diameters of metric or unified screw threads. The anvil and spindle have a 60° point for fitting into thread grooves.
