What is 3/8-24 unf-UNC / UNF plug gages GGRLD are designed to inspect the pitch diameter and functional thread for internalthread components All plug gages are available with Certificate of Accuracy documentation Gage dimensions according to ANSI/ASME B12 Short form certificate is supplied at no additional charge Long form certificate is available on request Thread gages are for UNC & UNF 3B class of fitDD is the major diameter of the thread Thus 3/8inch thread will have a 3/8 standing at the left most of the thread specification The dimensions usually come at margins of an inch (1/2, ¼, 1/8 ,1/16 etc) It must be noted that threads with a diameter smaller than ¼ have been given special numbers, from 0 to 10
