    Precision-Adjust Micrometer Heads

    Image of Product. Front orientation. Micrometer Heads. Precision-Adjust Micrometer Heads.
    For near perfect positioning, the spindle on these micrometer heads moves in smaller increments than the spindle on any other micrometer head we offer. Mount them in equipment requiring extremely precise adjustments, such as positioning tables used in semiconductor manufacturing or in optical component alignment. They are held in place by the cylindrical mounting hub using your existing brackets or fixtures. For a tight hold and extra support, secure the clamp nut against the bracket or fixture on the mounting hub.
    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.
    Round Spindle Tip—Round spindle tips minimize errors from misalignment, so they’re often used as feed devices.
