Tolerances better than tightest industry standards
Vacuum compatible screws available on demand
Ultra-Fine Adjustment Screws 9S127 are compact and provide extremely high resolution. Special design provides 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 tip or a blunt ground tip. The mounting surface of collars is either plain cylindrical or with a thread. The collars are ideally suitable for all mechanical stages and elements from STANDA or other companies. The handy dimensions of the knobs are optimally chosen to feel rotation as little as 0.5°-1°. This enables to achieve 0.5 μm positioning sensitivity. The knobs are made of hard aluminium and come in various colors: black, white, red, green, yellow, blue, etc. By default the knobs are in black or white color. Knobs come in 5 mm (standard), 10 mm or 15 mm length. When ordering, please append the standard screw code with the desired value for the length of the knob K10 or K15, example 9S127BM-7-K10. For screws with hexagonal hole (instead of the knob) see item 9SH127.
