Adjustment Screw, 170 TPI, 12.7 mm Travel, Large Knob

The AJS170-0.5K-NL Adjustment Screw has precision cut threads for exceptionally smooth adjustment and higher sensitivity than standard micrometers. The AJS170-0.5K-NL offers 0.5 inch (12.7 mm) precision travel obtained with included large adjustment knob, 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.
