One of the more frequent questions we receive is: I am tapping a ¼-20 UNC 2B internal thread with an “H13” tap, what gage do I need to inspect the threaded holes in my parts after tapping?

Imagine your task for this week is to develop a hand tool gaging solution for a large rotor with an ID of nearly 400mm. Given the size and the large diameter, it is unlikely the part can be brought to a gage or even a CMM for an in-process check.

Western’s Micro IIi Air Gage Readout provides fast and accurate measurements of internal and external diameters, tapers among other features.

Mahr Inc., a subsidiary of the Mahr Group, has over 160 years of experience providing dimensional measurement solutions to fit customer application needs.

For over 65 years Dorsey Metrology International, a certified women’s business enterprise (WBE), has been manufacturing high-precision mechanical and optical measurement equipment.

Today, there are myriad ways to breathe new life into existing gages without the need to invest in new gaging. Users are familiar with the gages they have. They may be under quality control cycles, are easy to use, provide good results, and have proven themselves over time.

Many company owners or managers are frequently asked by staff to consider bringing gage and instrument calibration in-house.

Digital gaging, involving the software and hardware used to capture and process digital measurements, has grown dramatically in the past two decades. It has also made quality more efficient and effective.

Settling measurement disputes should be an easy matter since they are all about numbers, but unfortunately it doesn’t work out that way.
