All About Thread Gages

By Frank Xu In Science & Technology Posted On September 12,2018 0 Comments

With increasing industrialization, work has become more machine oriented, and the need for smaller parts such as thread gauges has increased as their uses have widened. The gages are used to measure the accuracy of so many parts of the machine. Hence, a good quality gage is required to produce and establish great results.   

One tiny error can create chaos and a lot of loss and damage. There are so many kinds of thread gauges and finding the best one to suit your needs can be quite challenging. Here are a few things you can keep in mind while getting to know the different gages and their uses:

  • Common features of the best thread gages:
  • They are wear and tear resistant.
  • Look out for standard availability. It is present in special models.
  • They need to be ISO certified.
  • The older steel has better stability to its dimensions.
  • Knurled handles are looked up to for better grip and secure handling.

Gages used to measure internal threads:

Gages, UNC thread gages used to measure internal threads of a component are categorized into two groups. The GO and the NO-GO gages. These are mounted on a common handle for thread diameters up to 40 mm and are designated as GO or NO-GO thread plug gauges. The GO thread plug gage checks the virtual size of the internal thread and the proper screw-in fit. It is used to check the smallest size of the internal thread pitch diameter and also checks the smallest size of the major diameter. The NO-GO thread plug gages are used to check if the actual pitch diameter of the material’s internal thread exceeds the largest specified size. The NO/NO-GO thread plug gage is a mix of both GO and NO-GO thread plug gauges and work together on one handle. The GO/NO-GO thread plug gages have the benefits of both NO and NO-GO gages in it.

Analog and Digital Thread Plug Gages:

Analog and Digital Thread Deep Plug Gages are another kinds of gages that are involved in measuring the thread depth in a single operation and are used in components with same thread sizes, but different depths and it can be easily adjusted to a number of variants without the use of auxiliary tools.

These are some of the things one needs to remember before choosing a gage. Not only is choosing the right gage necessary but also using them properly will promote their quality, productiveness, and liability. Good thread performance is based on perfect inspection and gage calibration, as well as meeting current thread inspection standards. One of the advantages of using a thread depth plug gage is that it can be easily adjusted to a number of variants without the use of other aiding tools.

They must be handled safely, and they need to be stored under better conditions. They come in different sizes and are used to measure the different level of depth. They are easy to adjust and also come along with a locking screw.
