Webb28 mars 2024 · So the pitch of the screw gauge is $ \dfrac{1}{2}mm $. Now, we know that the least count of a screw gauge is the pitch divided by the number of divisions on the circular scale. According to the question, the number of divisions on the circular scale is equal to $ 50 $. So the least count is given by $ L.C. = \dfrac{{1/2mm}}{{50}} = 0.01mm $ WebbScrew Gauge (or Micrometer Screw) In general Vernier Callipers can measure accurately upto 0.02 mm and for greater accuracy micrometer screw devices, e.g. screw gauge, spherometer are used. These consist of accurately cut screw which can be moved in a closely fitting fixed nut by turning it axially. The instrument is provided with two scales:
