Starrett Micrometer Heads
 |
Plain Thimble |
Mount 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.
Plain Thimble—Plain thimbles turn freely without friction or a stopping device and rely on operator feel for accurate measurements.
Nonrotating Spindle—Nonrotating spindles prevent scratches on delicate work surfaces and eliminate distortion of soft or elastic material.
Locknut—Locknuts lock the micrometer’s spindle in place.
