Precision 127 TPI Adjustment Screw, 12.7 mm, Large Knob, Side Lock

The AJS127-0.5K Adjustment Screw has precision rolled threads for exceptionally smooth adjustment and higher sensitivity than standard micrometers. The AJS127-0.5K 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. High-precision 127 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. A lock screw on the side secures the adjustment screw from turning.
