What Are Taperlock Thread Plug Gages Used For?
Taperlock thread plug gages are used to check the accuracy and dimension of parts that require high tolerances and a need for great accuracy, such as those used in the medical, automotive, oil/gas and aerospace industries.
A thread plug gage measures the dimensions of a part by entering or not entering the internal thread (inside the hole of a part as required).The Go end should engage and the Not Go(NoGo) end should not engage the part. This is known as fixed limit gaging.
Taperlock style (000 to 1.5 inches diameter sizes only): These gages have a tapered shank behind the threaded portion. They are firmly pressed into an aluminum handle that has a matched tapered hole. New gage members can be inserted into the existing handle.
Gage Assembly can produce high quality taperlock thread plug gages

Graphitic Tool Steel
All thread gages are made of the finest oil hardened graphitic tool steel available. Because of the graphitic lubricant qualities in this steel, (which reduces friction) and high carbon content, it produces superior long wearing qualities.
Hard Chrome
All standard thread plugs are supplied in hard chrome at no additional cost.
- Heat treated and cold treated for extreme stability.
- Lapped for extra precision and longer wear.

Root Relieved Thread Ring Gages
Thread ring gages are root relieved for longer and more accurate gaging life. A root clearance at the major
diameter eliminates any possibility of interference from the full form of the setting plug and major diameter of
the part being checked. This gives assurance that flanks of thread are making proper contact.
- Graphitic tool steel for superior quality and longer wear
- Heat treated and cold treated for extreme stability.
- Lapped for extra precision and longer wear.

Truncated Setting Plugs
Truncated extra length setting plugs insure more perfect size. Truncated set plug is the same as full-form set
plug except with crest of thread removed for approximately one-half length of gage, giving a full and truncated
portion. The full portion insures correct clearance and forms at major diameter of ring. Truncated portion
controls pitch diameter.
When using truncated setting plug, thread ring gage should be set on the full form of the set plug. The ring
should then be turned on the truncated form, and the “feel” should be the same as on the full form. If there is a
“shake” on the truncated form, this will indicate that the thread form of the ring is unsatisfactory and should
be discarded, or if possible, repaired by relapping.
- Graphitic tool steel for superior quality and longer wear
- Heat treated and cold treated for extreme stability.
- Lapped for extra precision and longer wear.
