These mechanical outside micrometers are the standard/classic micrometer design for most high-precision outside dimension measurements when higher resolution than a caliper is required.
- Operators open the jaw with the thimble and insert a workpiece between the measuring faces and close the jaws.
- The main scale is then read and then added to the graduations on the vernier scale to provide the exact measurement.
- They are commonly used to measure the outside dimensions of raw materials, whole workpieces, and features in production, QA, and inspection environments in both metalworking and other industrial applications.
