Thread Check carries an extensive inventory of quality Class ZZ plain pin gage libraries. Every set is supplied with a certificate of accuracy and traceable to the National Institute of Standards and Technology (NIST). Class ZZ Pin gauge sets may be used to measure hole sizes, calculate distances between holes, gage slot widths, and to check locations.
