Mitutoyo Micrometer Heads
With Ratchet-Stop Thimble
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. Spindle length is the maximum extended distance when the micrometer head is set at zero.
Ratchet-stop thimbles have a constant-force mechanism for repeatable measurements without relying on user feel. A speeder knob reduces the time it takes to open and close the micrometer. When the spindle stops tightening, the thimble stops turning, but the speeder knob will continue turning with a clicking sound.
Clamp nuts securely hold the micrometer head and provide extra support. Locknuts lock the spindle in place.
