Thread ring gage is adjustable and used to measure threads on an outside diameter (OD) to ensure the threads are within its designed tolerance limits. The thread ring gage is a one piece construction with a single setting adjustment feature, manufactured to an X tolerance and American Gage Design standards (AGD).

Thread ring gages are root relieved for longer life and more accurate gaging. They are manufactured with a root clearance in the major diameter which eliminates the possibility of interference from the full form section of the thread setting plug and major diameter of the part being gaged. This feature assures that the thread flanks are making proper contact.

Available in GO or NOGO, Class 2A or 3A for inch and to X Tolerance, Class 6g for metric. Class and tolerances conform to ASME/ANSI B1.2, ANSI B1.16M Gage Standard and/or H28 Handbook. All thread inserts are made of an oil hardening graphitic tool steel and are ring lapped and hand polished to ensure maximum wearability. Class W or UNJ threads quoted upon request. Adjustable ring gages are available in steel or chrome.
