F.A.Q. on Thread Gauges that you always Wanted to Know

Do you belong to the engineering industry? If you are coming across the term thread gauge for the first time, let us tell you that it is a fairly heard term in the mentioned industry. Basically, a thread gauge is a device that eases your labor of measuring the lead of the screw thread and profiling it on the basis of the results obtained.

Here are more information on Api Thread Gages and Gage Calibration that might interest you. We have shared them in the form of answers to frequently asked questions on this topic. Watch out!

Q.1.What is the specific use of thread gauge?

Ans.: The basic use of thread gauge is to estimate the pitch of the thread that you see on a regular screw. This tool is also used for measuring the pitch of the thread present in a tapped hole too.

However, if you consider the thread gauge as a mere pitch measuring tool then you might not be absolutely correct. This is because the device finds aggressive use for setting the profile of a screw based on the thread measurement and its shape as determined by this thread gauge.

Q.2. Does this gauge give 100% accurate results in interpreting the pitch of a screw?

Ans.: While you can remain confirmed that the thread gauge is a tool that makes it easier for you to make the profiling of a screw, you cannot be totally sanguine that it will measure the thread with 100% accuracy at the first go.

Therefore, keep your mind open that you have to implement the trial and error method and go on measuring the pitch of a given screw before you could finally generate the right metrics.

Simultaneously, remember that this trial and error method is more precisely applicable for screws that come from unknown origin where there is no idea of the source. Thus, it is better to say that the thread gauge works best for measuring the thread of pitch of screws that forms with thread patters that conform to the specific thread standards.

Q.3. What is the next step to be done when the right thread is identified by this tool?

A.: The first step you have to follow is to determine the thread of the screw. When is done, extend one of the leaves of the thread gauge and fit it tightly against the thread.

Here, you need to remember that if the teeth of the tool match with that of the incline of the thread of the screw then you can successfully determine the thread measurement. In case it is not so then you have to try with another leaf provided in the device.

When you have finally arrived at a conclusion, what you have to do is to read what measurement has been engraved in the leaf. Note it down as this is the measurement of the thread measurement of the screw.
