Use these micrometer heads in jigs, fixtures, machine tools, movable tables, and other equipment that require precise adjustments. They are held in place by the cylindrical mounting hub using your existing brackets or fixtures. All have a plain thimble that turns freely without friction or a stopping device and relies on operator feel for accurate measurements. Spindle length is the maximum extended distance when the micrometer head is set at zero.

Clamp nuts securely hold the micrometer head and provide extra support.
