An inside micrometer is a device designed to precisely measure things such as the inner diameter of holes. Where a standard micrometer might be used to measure the outer diameter of a bolt, an inside micrometer could be used to measure the inner diameter of a nut. There are several designs for the inside micrometer, though they all perform this same basic function. All micrometers are designed to make very precise measurements, but the micrometers themselves can be either small or quite large. Each inside micrometer will have both a minimum and maximum diameter it is able to measure, so it's common to find inside micrometer sets.Part No. | Range | Rod | Resolution |
