Product Description
AJS Series Adjustment Screws have precision rolled threads and proprietary lubrication for exceptionally smooth adjustment and higher sensitivity than standard micrometers. With sub-micron sensitivity, they are a cost-effective alternative to micrometers where position readout is not required. The standard 0.375 in. (9.5 mm) diameter collet allows them to be used with Newport optical mounts, stages, and most micrometer-compatible components. Our miniature series adjustment screws are ideal for OEM and custom mount applications and the 20 TPI coarse adjustment screws are useful for quick travel adjustment where high resolution is not required.
