Variable Threaded Hole Location Gages

If you want the ultimate in Threaded Hole Location Gage, get the Variable Threaded Hole Location Gage. This is made by only one gage maker and is really a fairly complicated device. The threaded end of the Variable Threaded Hole Location Gage has two sets of balls, one set at each end of the thread. The Variable Threaded Hole Location Gage is screwed into the product thread, then the balls expand into the pitch diameter of the thread. The balls are the Best-Wire-Size diameter and seat in the internal thread pitch diameter cylinder. By being located at both end of the thread, they give a true picture of the position of the thread.
The Variable Threaded Hole Location Gage is many times more expensive and not without its other possible faults. First, being a manufactured mechanical device it has many moving parts and there are potential tolerance build-up problems within the Variable Threaded Hole Location Gage. Second the Variable Threaded Hole Location Gage may have to be built to order for your standard thread size because it is not an on-the-shelf item. Third, to calibrate this tool you will need a master threaded ring gage which is not inexpensive either.
