Functional size thread inspection is fast, easy to use, affordable, and versatile for inspecting threads. The Gagemaker PG-6000 and RG-7000 functional gages use two precision ground thread rolls that seat into the thread form and contact the thread at the pitch line. The gages are zeroed at a preset calculated thread size. Deviations from nominal size are read on the indicator. Thread rolls are able to determine variations in form, lead, taper, and height all simultaneously just as the thread plug and ring gages do. The PG-6000 and RG-7000 are set using gage blocks, micrometers, or Gagemaker’s MIC TRAC measurement center. Thread ring and setplug masters are not required.
The PG-6000 Series gages inspect diameters of internal threads. The RG-7000 Series gages measure diameters of external threads.
Common pitches ranging from 4 TPI to 20 TPI of the UN Series, ACME, and Stub ACME, and 1.5mm to 4 mm of the ISO Metric thread rolls are in stock. Whitworth and 7° X 45° Buttress thread rolls are available with short lead time.
With the PG-6000 and RG-7000, thread diameters up to 24 inches can be easily and accurately measured.
