What is a Micrometro?

A micrometro, also known as a micrometer screw gauge, is a precision measuring instrument designed to measure linear dimensions with extreme accuracy. It typically consists of a fixed anvil, a movable spindle with a thimble, a ratchet stop, and a scale engraved with fine graduations.

Types of Micrometros

Micrometros come in various types to suit different measurement needs:

• Outside Micrometros: Measure the external dimensions of objects, such as diameters and widths.
• Inside Micrometros: Measure the internal dimensions of objects, such as bores and grooves.
• Depth Micrometros: Measure the depth of holes and recesses.
• Special-Purpose Micrometros: Designed for specific applications, such as measuring threads and sheet thickness.

Key Features of Micrometros

• High Precision: Micrometers can measure dimensions with an accuracy of 0.001 mm (0.0005 inches).
• Repeatability: Consistent and reproducible measurements ensure reliable results.
• Long Travel Range: Micrometros offer a wide measurement range for versatility.
• Ease of Use: They are simple to operate, making them suitable for both experienced and novice users.
