Product Name Notes
External Pitch Diameter Gage 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...
Internal Pitch Diameter Gage 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...
Internal Functional Size Thread Inspection Gage 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...
External Taper Gage 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.
Internal Pitch Diameter Gage 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...
Internal Taper Gage 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...
Small Diameter Internal Functional Size/Pitch Diameter Gage 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...
External Functional Size Thread Inspection Gage 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...
External Pitch Diameter Gage 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 Gage 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...
External Thread Height Gage
Internal Thread Height Gage
Thread height is the distance between the crest and the root of the thread, normal to the axis of the thread. Several issues are easily detected by simply inspecting thread...
Thread Lead Gage Thread Lead is probably one of the most important thread elements if not the most important in the thread cutting industry. Lead error (which often leads to standoff error on...
Buttress Runout Gage Thread runout is the measurement of the abruptness with which the buttress thread is terminated at the triangle end of the thread. A rapid pull-out of the cutting tool results...
