Our popular AJS Series Adjustment Screws provide exceptionally smooth, repeatable adjustment for ULTIMA^® optical mounts. High precision 100 or 127 TPI rolled stainless steel threads are mated with an aluminum-bronze collet. This combination of materials is a superior match for stictionless movement and long life.
Our patented thread pitch lock securely locks the adjustment screw with just a simple turn of a set screw, without influencing the position of the front plate of the mount. Two versions are available, one with the set screw on the end next to the drive screw and a second with the set screw on the side for easier access when used with a knob or in an optical system.
