Diametres of various objects can be measured br using a micrometre screw gauge: Readings can be obseved by adapting following steps 1-Main scale reading;when one revolve the THIMBLE a scale appears with divisions 2-Circular scale reading;the digit apearing on circular scale conciding with the main scale. Main scale readind+(Circular scale reading into Least count) yields answer following link can be fruit ful for better techniques http://www.tutorvista.com/content/physics/physics-i/measurement-and-experimentation/screw-gauge.php Regards:MALLICK TAYYAB
The distance between each line of the body is equal to 0.5 mm.
Gauge the distance between each line is equal to 0.01 mm.
there is a website of the diagram.

A micrometer screw gauge is commonly known as a micrometer. This is a form of calipers used for measuring small dimensions. Screw gauge in extensively used in the engineering field for obtaining precision measurements. The article describes the principle and main parts of a basic micrometer screw gauge.
The zero error in the vernier calipers and micrometer screw gauge when the O mark on the main scale is not in line with the pointer.
the inventor of micrometer screw gauge is William Gascoigne.
A "screw pitch gauge" is used to measure screw pitch. Typically, the gauge has a number of indented templates for each standard pitch. Matching a particular template to the screw or nut gives the pitch. You can also use a measuring device (ruler, micrometer, etc.) to measure a group of threads and then "do the math" to estimate pitch. Accuracy depends on your ability to accurately measure length and count threads.
