2-3/4 x 12 UNJ-3B ~ Thread Plug Gage ~ Go-No/Go All gages guaranteed to be to the specs stated. Diameter T.P.I. Class Manufacture Go P.D. NoGo P.D. 2-3/4 2.7500 12 UNJ-3B Ponam 2.7094 --- What's The “J” In UNJ Screw Threads? The follown is from Thread Checks, Inc. website: UNJ, UNJC, UNJF and UNJEF threads are almost identical to UN, UNC, UNF, and UNEF threads except that the external J thread has a much larger root radius than the standard UN threads and inspection must be performed on this element. The Special UNJ threads are designated by the nomenclature UNJS. J screw threads feature a root radius which improves the tensile stress area of the fastener and helps to reduce the stress concentration factor in the thread thus making the thread stronger. Additionally, the requirement for high strength is achieved with 3A and 3B classes of fit. All pitch diameters and tolerances are based on the Unified Inch Standard. About These Gages: ALL Gauges we sell are thoroughly inspected to insure conformance to the specifications stated. Almost all the gauges we sell come from manufacturing companies and machine shops that had the misfortune of some bad luck and had to liquidate. We have found most had well cared for inspection equipment. All PLUG GAUGES are dipped in plastic for protection and shipping, we do however remove the coating for inspection and photography. I personally have spent over 45 years in the machining industry serving both military and medical. When it comes to understanding the requirements of inspection and thread gauges my expertise is in the top 1%. I personally inspect every gauge, although I do not check Pitch Diameters of every gauge, if it appears they need it, I will measure the pitch diameter to verify it is correct. All gauges that we sell that have apparent damage or potentially not to spec are discarded or so marked and discounted.
