What is Least Count of Screw Gauge?

The least count of screw gauges is 0.01mm.

The least count of a screw gauge refers to the smallest measurement that can be read or determined using the instrument. It is an essential parameter that determines the precision and accuracy of the screw gauge.

To calculate the least count of a screw gauge, we need to consider the pitch of the screw and the number of divisions on the circular scale.

The formula to determine the least count is as follows:

Least Count = Pitch of the Screw / Number of Divisions on the Circular Scale

The pitch of the screw refers to the distance traveled by the spindle in one complete rotation. It is typically provided by the manufacturer and can vary based on the design and
