Some Types Of Gauges And Their Advantages
35263 03/30/2018 Technology 188 /One uses screws, nuts, and bolts almost on a daily basis. These are the normal and basic tools in utility in the industry. These tools have use in every industry. However, do you know that you have to check the gauges of these threaded tools as well? In the production shops, they use the thread gauges like the UNC thread gauges to check the pitch of these simple threaded tools.
Main types of gauges
There are two kinds of gauges. They comprise the ring types and the plug types. They have completely different kinds of uses. You use the thread ring gauges to measure the accuracy of the threads on the outer portion of the rods or pipes. They are also useful to measure the pitch of the screws. The thread plug gauges have the utility of checking the accuracy of the threads in the inner portion of the holes and nuts, etc.
Based on the nature of the machinery, you can find three types of gauges. They are the Pitch gauges, NPT thread gauges, and the NPTF gauges. We shall look into each of the three types of gauges in brief.
Pitch Gauge
This is the basic thread gauge. Industry workers use this gauge to measure the pitch of the screw head. This is not a precision tool. It allows the user to determine the profile of the given thread. They use it to categorize the thread by the shape and the pitch. The main advantage of these kinds of thread gauges is that it does not take much time for measuring and calculating the thread pitch of the screw.
NPT Gauge
The full form of the NPT Gauge is the National Pipe Thread Taper Thread gauges. You use these ring type of gauges to check the accuracy of the external threads such as those on screws etc. At the same time, the plug types have use to measure the accuracy of the internal threads. These are precision tool instruments.
NPTF Gauge
The National Pipe Thread Fuel gauge has to meet higher standards. They have the basic uses as well. In addition, these NTPF fittings are precise tools forming a kind of a dry seal when you tighten them. These thread gauges have utility for checking the accuracy of the thread crest and the root. The crest and the root form the highest part and the lowest part of the screw. You also use these gauges to check the pitch of the screws.
There are many advantages. We shall consider the most important ones alone.
The industry worker would be able to inspect the full thread profile and the pitch of the screw as well.
You do not require much of training to master this process. In case you are able to use the Go and the No Go thread gauges properly, you can make a fair judgment whether the component is good or bad.
We have seen some simple forms of gauges in this article. These are extremely useful implements in the manufacturing industry.
