This GF Gage 9/16-18 UNF-2A GO thread ring gage is used to check external 9/16 in, 18 TPI Unified Fine threads to Class 2A tolerance. The face is etched GO PD .5250, so it verifies the pitch diameter limit of the thread under inspection. It is a split, adjustable-style ring with two holes through the face, and a knurled outer diameter for hand gaging. It is made in the USA and is sold new. The box label shows number 55332571 and a 9/16-18 UNF 2A set plug description, so confirm the set plug is not required before purchase.
