Ultra-Fine Adjustment Screws 870-0080

  • Stainless steel screw with pitch of 0.25 mm
  • Precision brass collars of 3 types
  • Tolerances better than tightest industry standards

Ultra-Fine Adjustment Screws 870-0080 are compact and provide extremely high resolution. Special design provides a smooth and repeatable action by mating a high precision 0.25 pitch stainless steel screw with a high precision brass collar. The screws have either a hardened steel ball on the top or a blunt ground tip.

 

The mounting surface of collar is either plain cylindrical or with a thread. The collars are ideally suitable for all mechanical stages and elements. The handy dimensions of the knobs are optimally chosen for fingers to rotate a knob with 0.5°-1° resolution. This enables to achieve 0.5 µm positioning sensitivity. The knobs are made of hard aluminium and come in various colours: black, white, red, green, yellow, blue, etc. By default the knobs are in black or white colour, 5 mm thick.
