Coarse Adjustment Screws

   Our 40TPI 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.
   40TPI series coarse adjustment screws have 40-pitch threads and hard ball tips for exceptionally smooth adjustment.  The 40TPI's thread pitch is the same as a standard micrometer but does not include a location scale on the barrel.
   40TPI 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.
