Using a Thread Gage Correctly: 3 Tips to Get You Started

Do you know how to use a thread gage? If the results of your tests are routinely inconsistent and unpredictable, there is a significant chance that you are not using the device the correct way. Make sure you know how to use a thread gage in order to get the most from the device.

1. Be Careful

It's essential you use a great deal of caution when you need to use a thread gage. If you use too much force, you will not get accurate results. Mainly when you are testing with more delicate materials, like a plastic screw, if you use too much force, you will inadvertently jam the gage into the threads. 

Forcing the gage into the threads will render an inaccurate reading. You should take your time and gently ease the device in, and if you meet a great deal of resistance, you might need to alter the configuration altogether. 

2. Review the Rating

If you routinely use more than one gage, it's a good idea to look at the rating of the gage before you use it for testing. If you fail to perform this step, you might run into some discrepancies. The reason this step is so important is that different countries have different rating standards. 

For this reason, using a gage rated for one country to test a thread engineered and manufactured in another country might give you an inaccurate reading, which could be false. Always use a gage that meets the same rating standards as the origin of the thread you want to test. Keep in mind that some countries do have similar ratings, but you will need to know this information beforehand.

3. Remember to Calibrate

A thread gage is a device that you can get a great deal of use from; however, long-term use does take some work on your part. Make it a point to calibrate the thread gage routinely. Calibrating is a way of resetting the device. If you do not calibrate the gage, the gage variation of the device will not be reset and accurate.

As a result, any testing that you perform with the gage going forward will not be accurate. To calibrate correctly, you will likely need to use a calibration gage. Research your specific gage to determine how often the device needs to be calibrated for the best result. 

With your increased knowledge and a quality gage, you will find greater results and find it easier to perform your qualitative test and ensure your results are accurate.
