The most compelling reason to select the micrometer Screw over the Vernier caliper is the guarantee that when measuring a flexible surface, the same amount of pressure is applied between samples. The Vernier caliper has the ability to measure internal and externally, but if precision is required, the micrometer screw is the tool of choice.

What is the difference between Screw Gauge and Vernier Caliper?
*Micrometer have a rotary handle and whereas vernier have a slider. *Micrometer is for measuring diameters while vernier is for measuring inside & outside diameter as well as depth. *Least Count of Vernier Caliper is 0.02mm *Least Count of Micrometer is 0.01mm
Why screw gauge is more precise?
A screw gauge has a smaller pitch than a Vernier caliper, which allows for more precise measurements. The screw gauge also provides a digital reading, which reduces human error in reading measurements. Additionally, the screw gauge has a finer scale that allows for more accurate readings compared to a Vernier caliper.
What is micrometer screw gauge used for?
A micrometer , sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw used widely for precise measurement of small distances in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are similar in use to vernier calipers but are more precise although the modern digital caliper has blurred the distinction between them.A micrometer is also used to measure the diameter of very small objects that a vernier calliper can't measure for example a screw or a piece of wire.This instrument is mainly used by mechanics.
How would be the reading differ if the screw gauge is used instead of vernier calliper to measure the thickness of glass plate?
Verniers give you a less accurate approximation of the thickness, whereas a micrometer can give a more accurate measurement, often by 100 orders more accurate.
What is the least count of screw gauge and vernier calipers?

What is the least count value of vernier caliper and screw?

What is the 'zero error' in vernier calipers and micrometer screw gauge?
In vernier calipers, zero error is when the jaws of the caliper do not close properly when they are in contact without measuring anything, resulting in a measurement that is not accurate. In a micrometer screw gauge, zero error occurs when the flat end of the spindle does not perfectly align with the reference line on the sleeve at zero reading, leading to inaccurate measurements.
What are the similarities between vernier caliper and micrometer screw gauge?
both are used in accurate measuring in a wide range of environments
What instrument measures the volume of a screw?
A micrometer (or micrometer screw gauge) measures the volume of a screw.
How reading differ if screw gauge is used instead of vernier calliper to measure thickness of glass plate?
Vernier caliper has an accuracy of 0.01 cm. But screw gauge has still more. It will be able to give even 0.001 cm. So even third decimal could be got accurately when we use screw gauge instead vernier caliper.
How do you read micrometers?
Difficult to explain without diagrams, but the micrometer relies on an accurate screw which advances the caliper a precise amount with each revolution. So you turn the screw until the object is lightly held, then read the axial scale and add on for the number of screw turns above the nearest scale reading. The most accurate type also have a vernier scale for very small distances. I suggest you look at Wikipedia 'Micrometer' which has a thorough explanation with diagrams.
