1/4-inch Adjustment Screws

   Our 170TPI series adjustment screws are useful for use in OEM and custom applications.  They 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.

   170TPI series ultra-fine adjustment screws have 170-pitch threads and hard ball tips for exceptionally smooth adjustment.  The 170TPI's thread pitch has over 3 times the resolution as a standard micrometer but does not include a location scale on the barrel.
