Micrometer heads are precision measurement tools that are designed as mounts onto other measurement instruments or precision fixtures. Used for measurement, positioning, and adjustment, micrometer heads are typically found on measurement jigs. More recently, these handy little devices have been found in use on precise feeding devices and cross-travel states on both manipulators and laser instruments. Given the growing range of applications for micrometer heads, the design options for these tools are also expanding. Micrometer heads can be customized based on their range of measurement, their type of stem, and their body size. Each part of a micrometer head can be specialized for the intended purpose with different spindle tips and leadscrews that are available.
