There are many types of threads. Some of these threads include a thread gauge, UN thread and NPT thread gauge. If you are planning on having a company manufacture threads for you, then you need to be very specific. Being specific will ensure that you get the right threads. If you happen to give wrong information, then you may end up getting thread gauges that aren’t of any benefit to you. When you are trying to choose a type of thread, you need to look at the following:
Tapered or parallel
Threads can either be tapered or parallel. So, what type of threads are you looking for? You should always be sure about what you want before you can make an order. However, you will need to know the difference between the two types of threads. Tapered threads have a smaller diameter as you approach the end. This is very different from parallel threads which have the same diameter from one end to the other. Therefore, you need to know whether the NPT thread gauge you need should be made of tapered or parallel treads before making any inquiries.
Pitch and size
When it comes to a UN thread gauges, measurements are everything. Without the proper measurements, you will get a thread that is bad. When offering measurements, you need to know the distance between each thread. This can always be done by measuring yourself or asking a professional to do the measurements for you. This way, you will be certain that you will get the right thread.
When you are trying to get a certain thread, you need to visit several manufacturers so that you get to know whether they are in a position to make the same for you. You need to know whether they have the right tools to make the same NPT thread gauge you have. You also need to know whether they have the right experience when it comes to dealing with these threads. Basically, you just need to make sure you get a company that has done this before. If the company you would like to buy a UN thread gauge from has been manufacturing good products, it will be able to take care of your needs too.
