AJS Series Adjustment Screws have precision rolled threads for exceptionally smooth adjustment and higher sensitivity than standard micrometers. They are ideal for use with Newport optical mounts, stages, and most micrometer-compatible components. With sub-micron sensitivity, they are a cost-effective alternative to micrometers where position readout is not required.
Engaging or disengaging our patented thread-pitch lock, now standard, won't influence the screw position. The knobs feature an integral hex hole for increased adjustment sensitivity.
High-precision 127, 100, or 20 TPI, rolled stainless steel threads are mated with the collet and proprietary lubricant for stictionless movement. The standard 0.375 in. (9.5 mm) diameter collet is threaded with a nut for mounting to optical mounts and stages. Our miniature series adjustment screws are ideal for OEM and custom mount applications. 20 TPI coarse adjustment screws are useful for quick travel adjustment where high resolution is not required.
Our patented thread-pitch lock secures the adjustment screw from turning by simply tightening a setscrew. Versions with knobs have the lock screw on the side, while hex versions have the lock screw conveniently located on the end next to the drive screw. A single wrench is used for both adjustment and locking. Non-locking, 0.5 in. (12.7 mm) travel versions are also available for use in optical mounts.
We offer these screws in 0.25, 0.5, 1, and 2 in. (6.35, 12.7, 25.4, and 50.8 mm) travel, with a knob or with hex adjustment. KD.37 and KD.75 stainless steel knobs are available as an accessory for use with the hex versions.
