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.
