How to use screw guage?
Answers
Answer:
Using Micrometer Screw Gauge
Just like a vernier calipers, a micrometer screw gauge also carries two scales – a main scale and an auxiliary scale. The main scale is a millimeter scale graduated to 0.5 mm, whereas the auxiliary scale is divided into 50 equal divisions. The auxiliary scale is on the thimble of the screw gauge and measures hundredth of the measurement. The jaws of the gauge are moved rotating the thimble. The auxiliary scale on the thimble is also known as the vernier rotating scale. Moreover, the thimble is so adjusted that 2 revolutions of the thimble will allow the jaws to move by 1 mm. This means that a single rotating will move the jaws only by 0.50 mm. The main scale lies on the part of the screw gauge known as the “sleeve”.
