Gravity. o screw gauge is the suitable instrument that achieves the required accuracy. Least count of circular scale = 1mm/100 = 0.01 mm. This micrometer is of a slide’s shape and size and has a mount of very finely graduated scale. When it comes to measuring cylindrical or spherical objects, an outside micrometer would be the best tool to use. Micrometer screw gauge is used for measuring extremely small dimensions which the vernier caliper cannot measure. ii. Inside micrometers usually come in a set that includes a micrometer head, various length spindles (or extension rods) that are interchangeable, and a spacing collar that is 0.500 inch in length. Search in STARRETT catalogs and technical brochures on DirectIndustry and find the information you need in 1 click. Figure: Diagram of Microvilli. As 1 mm has 1000µ, one division of stage micrometer is equivalent to 10µ. Proper Use and Care .
