Where can you use a micrometer screw gauge?

In mechanical engineering & machining.

It is used anywhere when we needed to measure small distances.

How do you read the scale?

Linear scale (1 mm interval)

Lower linear scale (0.5 mm interval)

Rotating scale (50

mm interval)

How do you read the scale on a Micrometer Screw Gauge?

Firstly, check for the zero error.

How do you read the scale on a Micrometer Screw Gauge?

Read the reading on the linear scale reading and add with coinciding circular scale multiply by least count.

Reading = Linear scale reading + (Coinciding circular scale x Least count) = 2.5 mm + (46 x 0.01)= (2.5 + 0.46) mm = 2.96 mm
