Screw checkers provide a quick way to measure standard threads. They provide all the information you need for screws; diameter, length, threads per inch, hole size and even tap drill sizes.
Chris Chris' Tips
These things are quicker and more accurate than using a pitch gage and caliper to measure threads. Simply try the threaded part in the holes until you find the proper one. No guessing or interpretation.
