Thread Check Inc. offers a full range of Gagemaker pitch diameter gages to verify that part pitch diameter is within specification. The Gagemaker PD gages measure the pitch diameter internal and external product thread.
Pitch diameter is the most important characteristic on a thread because it reflects the widest spectrum of possible defects. An out of tolerance pitch diameter can compromise the load capacity of a threaded component. Pitch diameter is perhaps the most important element with regards to whether two parts will screw together. Pitch diameter is the distance from the pitch line to the corresponding pitch line located 180 degrees around.
All threads have a pitch diameter whether they are a straight or tapered thread. However, some threads have pitch diameters that are measured via their crest diameter (diameter from crest to crest) instead.
The Gagemaker PD gages are adjustable within a wide size range and use interchangeable contact points to measure different pitch threads. Setting dimensions for the PD gages are generated with the TDWIN Thread Disk software. Gages require setting with either a MIC TRAC™ or other means (i.e. gauge blocks, micrometer, standard, etc.). Software, MIC TRAC™, and contact points are sold separately.
External PD gages can measure P.D. on diameters up to 12.00". Internal PD gages can measure P.D. on diameters from 1 1/2 up to 24".
Contact points are available for a range of threads and pitch sizes including UN series, Metric series, Acme, Stub Acme, 7x45 Buttress, and trapezoidal threads.
The Gagemaker PD Series pitch diameter gage is accurate, versatile, and economical.
