If you are using UN thread gauges or other thread gauges in your manufacturing unit as an inspection tool to establish the accuracy of the threaded components that you are manufacturing, make sure that you invest time to learn how to take good care of them. If your thread gauges and thread taps are not handled correctly or if they are not taken good care then you will not be able to get the best value for your money.
Before you start using your ACME thread gauges or any other thread gauge that you are required to use, learn how to use them correctly. Train those who are required to use the tool correctly. If they are not trained then they will damage the tools. Most of us think that thread gauges are very simple tools and that we do not require any training to use this too. While it may be true that the thread gauges are simple tools, it is not true that it does not require any training.
Ensure that the tool is well maintained and follow the usage protocols correctly. Here are a few usage protocols to remember when using your thread gauges. Before every use the thread gauges should be cleaned. If there are any dust particles or if there are other residual particles from previous use, they could damage the thread gauge and also the component that is being tested. Ensure that you are not skipping this step if you do not want to frequently damage your thread gauges.
Similarly, after the use, the thread gauges should be cleaned too. It is vital that you check whether there is any bur sitting on the grooves because if you are testing newly tapped threaded components, you will have this issue. You should also clean the thread gauge of any lubricant and oil residue that comes from the component that was tested or inspected. Before cleaning the thread, gauges do not store them in their respective sheathes.
While cleaning the thread gauges use soft cleaning material and do not use any chemical-based agents for cleaning that has the potential to corrode the surface of the thread gauges. You should also ensure that the thread gauges are not stored with any oil residues in them because such residues will damage the surface of the thread gauges.
When you are sourcing your thread gauges itself you should instruct the manufacturer to clearly mark the thread gauges so that you are always using the right thread gauges for the inspection. Do not mix up the thread gauges and their protective sheathe while storing because the next time when you are required to use them, you will end up facing problems.
Besides all these, you should also know that all the thread gauges have their own life span and the maximum number of times for which they could be used. When such limits are reached you must replace the tools promptly.
