Pitch Diameter Measurement Gages   Pitch Diameter Print This Data Sheet PD-6000 Series Print Operation Manual PD-8000 Series Print Operation Manual  How To Order Select the PD-6000 (internal threads) or PD-8000 (external threads) series gage model, based on the range of diameters being measured. Select the contact point model, based on the thread form (not included in price of gage and sold individually). Specify the pitch. The PD-6000 Series gages inspect pitch diameters of internal threads and the PD-8000 Series gages measure pitch diameters of external threads. Before inspecting parts, the gages must be preset to a nominal predetermined dimension using gage blocks, micrometers, or Gagemaker’s MIC TRAC measurement center. To ensure maximum accuracy, the gages use matched sets of precision contact points that seat at the pitch line of the part during inspection. The contact points are interchangeable to allow measuring different thread pitches. Contact point diameters are manufactured to tolerances of +.0002” and measurements are based on the proven three wire inspection method and technique. Contact points for common pitches ranging from 1 TPI – 18 TPI of the UN Series, ACME, Stub ACME, and 7° x 45° Buttress and 1.5 mm – 4 mm of the ISO Metric thread rolls are in stock. Special sizes available upon request. All contact points are sold individually and are not included in the price of the gage. Feature - Measures internal or external threads for a range of pitch diameters (see tables below for    ranges available). - Uses interchangeable contact points for measurement of different thread pitches. - Replaces conventional ring and plug gages by providing actual diameter readings. - Eliminates unnecessary damage to threads caused by ring and plug gages. - Allows use in a manufacturing or field environment due to durable construction. - Requires presetting using gage blocks, micrometers, or Gagemaker’s MIC TRAC    measurement center.
