Internal Pitch Diameter (1½” to 27″ Diameters) 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...
Gagemaker also manufactures functional thread inspection gages that inspect internal threads ranging in diameter from 1.5″ to 24″. The gages are adjustable within a size range and use interchangeable thread...
Gagemaker’s external taper gages inspect variation in connection taper. External taper gages are shipped with .072″ diameter contact points as standard. Select the proper contact point for your particular connection.
Gagemaker’s internal diameter and groove gages measure variation in internal bore diameters. Setting dimensions for the pitch diameter gages are provided by the TDWIN Taper software. Gages require setting with...
Gagemaker’s internal taper gages measure variation in connection taper. Taper gages are shipped with our standard set of .072″ diameter contact points (T072), unless specified otherwise. IT-6001 includes one set...
Pitch diameter and functional size inspections are pivotal to nearly every threaded connection. This can be especially true in smaller diameters, but these smaller diameters require a unique gage design...
These functional size inspection (or “GO/NO GO”) gages measure external thread diameters ranging from ⅝” – 24″. The gages are adjustable within a size range and use interchangeable thread rolls...
These rod style setting standards are used to set many JSS inspection gages for rotary shouldered connections. Standards for other connections may be available, contact us for more information.
Thread addendum is now a mandated inspection according to the API 5B Specification 16th Ed. Gagemaker also manufactures several models of thread addendum (a.k.a. shave) gages. Please specify the type...
