Coarse Adjustment Screws

   Our 20TPI adjustment screws incorporate our one wrench design for capstan adjustment, hex drive, and locking.  The unique collet design incorporates a split clamp for presetting the feel of the adjustment screw as well as locking
the screw movement.  If the location of the locking screw is not desirable, simply back it out and replace in the opposite side.
   20TPI series coarse adjustment screws have 20-pitch threads and hard ball tips for exceptionally smooth adjustment.  The 20TPI's coarser thread pitch is another alternative to a standard micrometer with less resolution.
   20TPI adjustment screws, except hex versions, come standard with black Soft Touch knob caps.  For axis color coding, red, green, yellow, and gray knob caps are available at no extra charge.  To order, add: -R (red), -GN (green), -Y (yellow), or -GR (gray) to the end of the Model Number.
