$$10 + 0.05 = 10.05 \text mm$$
A vernier screw gauge, commonly known as a , is a high-precision measuring instrument designed to measure very small dimensions—such as the diameter of thin wires, the thickness of metal sheets, or the size of ball bearings—with an accuracy typically up to 0.01 mm . vernier screw gauge
The screw gauge operates on the : when a screw is rotated, it moves a specific linear distance along its axis. Key Components $$10 + 0
