Product Description
The Starrett 210AP Screw Thread Comparator Micrometer is a quick and easy tool for measuring the accuracy of screw threads. It’s ideal for use in screw-cutting operations, measuring in small grooves and recesses, where regular micrometers fall short.
It has a 0-7/8″ measuring range and 0.001″ graduation, which makes it ideal for small measurements in tight spaces. The low profile design makes it easy to use on short sections of threads so you can determine whether they are within tolerance.
This model does not measure pitch diameter, however—if you need to measure that, we recommend getting another model, such as the 575 or 585 Thread Micrometers.
