Hex Adjustment Screw, 127 TPI, 6.35 mm Travel, End Lock
Model: AJS127-02H
Product Series Overview
AJS High-Precision Adjustment ScrewsThe AJS127-02H Adjustment Screw has precision rolled threads for exceptionally smooth adjustment and higher sensitivity than standard micrometers. The AJS127-02H offers 0.25 inch (6.35 mm) precision travel obtained with hex-head adjustment, 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.
TPI for Every Application
TPI stands for threads per inch and Newport's AJS screws are available in five different thread pitches to cover the sensitivity requirements of every application. Higher TPI provides for a shorter thread pitch with higher sensitivity to a 1° rotation of the adjustment screw. High-precision 254, 170, 127, 100, or 20 TPI, rolled stainless steel threads are mated with the collet and proprietary lubricant for stictionless movement.
Patented Non-influencing Locks
Our patented thread-pitch lock secures the adjustment screw from turning by simply tightening a setscrew. Engaging or disengaging the thread-pitch lock, now standard, won't influence the screw position. 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, 12.7 mm travel versions are also available for use in optical mounts.
Faster Alignment Times
High TPI adjusters have a clear sensitivity and alignment time advantage. This graph shows the results of alignment time testing of the Ultima Mirror mount with adjustment screws having 80, 100, 127 and 170 TPI.
Choose the Sensitivity You Need
170 TPI AJS adjustment screws provide a significant improvement in sensitivity over typical adjustment screws. 254 TPI versions are now available.
Sized to Fit Mounts and Stages
Newport's AJS adjustment screws have 9.5 mm industry standard mounting shanks allowing them to fit most optical mounts and linear stages where micrometer heads can be used.
