Screw Thread Micrometers

A screw thread micrometer is a precision tool that uses a screw thread to measure the pitch diameter and depth of threads. This measurement starts from the base of the thread to the crest of the thread, which is the “major diameter.” The major diameter determines how much space there is between two adjacent threads on an object.

They can be useful for measuring threads on bolts, screws, nuts, and other fasteners. When using a screw thread micrometer, it’s important to know what you’re measuring. Since there are different types of threads, they require different methods for measuring them accurately.

The best applications for these tools are in manufacturing and engineering since there’s frequent use of screws in machinery and equipment. Automotive repair shops where that fasten parts together with different types of screws could benefit from screw thread micrometers, too.
