A micrometer is a hand tool device which is used to measure small and accurate distance or diameter and a calibrated screw is used along with this micrometer for the measurement purpose. The distance of an object which is to measured, is known by adjusting and rotating this calibrated screw. The measurement is taken by measuring the distance the screw has moved from the face of the micrometer. It also has a digital LCD display which shows the reading taken by the micrometer.

| Types of Micrometers || Specialized Micrometers |
There are three main types of micrometer.
Outside Micrometer - Also know as external micrometer, this type of micrometer is basically used to measure wires and blocks.
Inside Micrometer - Also knows as internal micrometer, this type of micrometer is generally used to measure hole diameter.
Adjustable Depth Micrometer - This type of micrometer is used for measuring depth of slots.
Along with these main types of micrometer there are some specialized micrometers also, the list of these are as follows -
Bore micrometer - It is used to measure the inside distance of a hole
Tube micrometer - It is used for measuring the thickness of tubes
Digital micrometer - It shows the distance result in digital format
