It is not enough that you spend a lot of time trying to find the best manufacturer of NPT thread gauge or UNC thread gauges. You need to also ensure that you learn how to take care of your thread gauges. If you do not know how to take good care of the thread gauges, you will spend way more than you should on these inspection tools. You will be forced to replace your thread gauges more frequently than required.
You are required to maintain the thread gauges well and also store them correctly. Some of the most common storage mistakes made contribute to faster damaging of the thread gauges. If you have UNC thread gages or NPT thread gages you must use them only in the designated workstations. They should not be tossed around from one place to the other. When using your thread gauges always ensure that the workstation is clean and free from dust, debris and dirt. Do not leave the thread gauges on the floor or unclean surfaces between uses. The thread gauge surface should be kept clean so that it does not increase the friction level while testing the threaded components.
While storing make it a point to always put back the thread gauges in their respective protective sheathes. The protective covers as well as the thread gauges should be marked clearly. This will save you from using the wrong thread gauge for testing the accuracy of the threaded components. If the thread gauges are misplaced in the wrong covers, then the one using it may not be aware of this but will try to get exert force while using the thread gauge. This will result in thread gauge damage. As you could see, you must first have a clear usage protocol and storage protocol. When using the thread gauges should be checked for the markings so that you ensure that you are using the right sized thread gauge for testing.
While storing the thread gauges should always go in their respective protective covers and while replacing the markings should be double checked. The lubricants, bur and other particles sticking to the thread gauge should be cleaned using soft cloth before storing. Presence of lubricants will result in surface corrosion. Presence of bur and other metal particles will increase friction while usage which in turn could damage the surface of the thread gauge or the threaded component.
The thread gauges should be packed carefully so that when it is moved from one place to the other, they do not jostle and get damaged. All these storage tips are just commonsense tips that help you keep the thread gauges safe from damages. If you are careless then the profile of the thread gauges will get damaged and once it is damaged you cannot use it for inspection. Therefore, you need to make sure that there are no exceptions while using your thread gauges. Store them safely and make them last longer.
