William Gascoigne invented it in the 17th century.
the screw gauge is an instrument which is used to measure length of an object.... the least count of an screw gauge can be found as follow.... l.c= pitch of the screw gauge no of divisions on main scale
The difference between screw gauge and spherometer is that spherometer can measure the dimensions of spherical surfaces but screw gauge cannot
Because it can measure gauge of wire and has screw type structure.

Archimedes invented Archimedes' screw.
The Archimedes screw was invented in 250 B.C.
the inventor of micrometer screw gauge is William Gascoigne.
A micrometer (or micrometer screw gauge) measures the volume of a screw.
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.
Ratchets are used to prevent extra pressure on the screw in the screw gauge.
