Pitch Diameter Gages – Straight

Pitch Diameter for Straight Threads, 0″ to 72″ Diameters

Pitch Diameter is one of the most important inspections for nearly any thread. In the past, pitch diameter was ignored as long as the ring or plug gage threaded. Now, using Gagemaker gages, you have more control over threading connections of marginal quality. The process of locating and measuring the pitch diameter takes less than a minute. This minute of inspection quickly decides the difference between good and bad.

Gagemaker pitch diameter gages, commonly known as ball PD gages, verify that your part is within allowable tolerances. Improperly sized pitch diameters compromise the load capacity of your threaded components. The ball pitch diameter gages indicate the pitch diameter size of the product’s external and internal threads. The gages are adjustable within a size range and use interchangeable contact points to measure different thread forms and pitches. Setting dimensions for the pitch diameter gages are provided by the TDWIN Thread Disk software.

External Pitch Diameter (0″ to 72″ Diameters)

The ball pitch diameter gages or “GO/NO GO” gages indicate the pitch diameter size of the product’s external thread. The gages are adjustable within a size range and use interchangeable contact points to measure different pitch threads.

Setting dimensions for the pitch diameter gages are provided by the TDWIN software. Gages require setting with either a MIC TRAC™ or other means (i.e. gauge blocks, micrometer, standard, etc.). Software, MIC TRAC™, contact points, and are sold separately. Rod style standards are available, please contact customer service for more information.

All PD-8000 gages are sold without contact points.

All PD-8000 gages are sold without contact points. Higher resolution and metric indicators are available.

Internal Pitch Diameter (1½” to 27″ Diameters)

Gagemaker-PD-6000-on-Part

The ball pitch diameter gages or “GO/NO GO” gages indicate the pitch diameter size of the product’s internal threads. The gages are adjustable within a size range and use interchangeable contact points to measure different pitch threads.

Setting dimensions for the pitch diameter gages are provided by the TDWIN software. Gages require setting with either a MIC TRAC™ or other means (i.e. gauge blocks, micrometer, standard, etc.). Software, MIC TRAC™, contact points, and are sold separately. Rod style standards are available, please contact customer service for more information.
