Thread ring gauges and thread plug gauges are essential measuring instruments for screw thread pitch and diameter. Nonetheless, there are a number of misconceptions regarding these gauges.

1. Common Misconceptions About Thread Ring and Thread Plug Gauges Debunked
Thread ring gauges and thread plug gauges are essential measuring instruments for screw thread
pitch and diameter. Nonetheless, there are a number of misconceptions regarding these gauges. In
this article, we will dispel some of the most prevalent myths regarding thread ring gauges and
thread plug gauges.
First fallacy: Thread Ring Gauges and Thread Plug Gauges are identical.
The notion that thread ring gauges and thread plug gauges are interchangeable is one of the most
widespread misconceptions about thread gauges. But this is not the case. Thread ring gauges are
utilised to inspect external threads, whereas thread plug gauges are utilised to examine interior
threads. They are constructed differently and therefore cannot be interchanged.
The second fallacy is that thread gauges only measure thread pitch
Another common misunderstanding is that thread gauges only measure the screw thread's pitch.
Although pitch is an essential measurement, thread gauges are also used to measure the thread's
diameter, thread form, and other characteristics. For instance, thread gauges can be used to measure
a screw thread's major diameter, minor diameter, and pitch diameter.
Third Fallacy: Thread Gauges are Simple to Use
Even though thread gauges are basic instruments, they can be challenging to use properly.
Inaccurate measurements can result from improper use, causing issues in the manufacturing
process. To properly utilise thread gauges, one must have a comprehensive comprehension of the
gauge's design, function, and specifications.
The fourth fallacy is that thread gauges are always accurate.
Another fallacy regarding thread ring gauges is that they are always precise. Although gauges of
high quality are designed to be precise, they can become worn or damaged over time. To ensure
that thread gauges remain accurate, regular calibration and maintenance is essential.
Fifth Fallacy: Thread Gauges Are Necessary Only for Precision Manufacturing
While thread gauges are indispensable in precision manufacturing, they have many other
applications as well. Thread gauges, for instance, are utilised to inspect the threads on bolts, nuts,

2. and other fasteners. In addition to piping, automotive, and aerospace applications, they are also
used in other industries.
Sixth Fallacy: Thread Gauges Are Expensive
Although high-quality thread gauges can be expensive, many businesses find them to be a
worthwhile investment. Accurate measurements are necessary for assuring the quality of the final
product, and the use of high-quality thread gauges can reduce the likelihood of errors and defects.
Seventh Fallacy: Thread Gauges Are Obsolete
Some individuals believe that thread plug gauges have been superseded by digital measurement
instruments. Despite the fact that digital tools can be useful in certain applications, thread gauges
continue to be an indispensable instrument in many manufacturing and assembly processes. Thread
gauges are straightforward, dependable, and accurate, and they are unlikely to be completely
replaced by digital instruments in the near future.
In conclusion, thread ring gauges and thread plug gauges are misunderstood in a number of ways.
These instruments are essential for measuring the pitch, diameter, and other characteristics of
screw threads, and their proper application is crucial for achieving accurate measurements and
producing high-quality goods. By dispelling these myths, we can better grasp the significance of
thread gauges in the manufacturing process.
