A Guide to Understanding Thread Plug Gauges

Thread plug gauges are used in many industries to measure the diameter of threaded holes. They can be used to determine how many threads per inch (TPI) a hole has and if it is too large or small for a given application.

The most common thread plug gauges are made from steel, brass and aluminium. Each of these materials has advantages and disadvantages when compared to each other. Steel gauges are more durable than brass or aluminium gauges because they don't rust as easily. Brass and aluminium gauges are often less expensive than steel but have lower tensile strength ratings.

Thread Plug Gauge manufacturers use several methods for making their products. Most companies use threading machines that automate the creation of thread plugs from finished parts. These machines guarantee consistent sizes, but they could be better; there will always be some variation in size between different pieces of material. Because of this, you must choose a gauge manufacturer that uses high-quality equipment for producing their products.

What is a Thread Plug Gauge?

A thread plug gauge is a tool used to measure the diameter of a thread. It is usually used to measure the diameter of a bolt head or the inside diameter of an irrigation pipe. The gauge may also be called a threader or tap handle.

A thread plug gauge has two parts that are separated by a flange. The upper part contains an internal thread gauge, usually brass, steel or aluminium. A threaded piece fits into this portion and measures the outside diameter of whatever it is being used on.

The lower part houses a tap handle, designed to fit over the end of the threaded piece so that it can be screwed into place with ease. This handle contains an internal thread plug that fits into the upper section and measures its inside diameter.

What Does a Thread Plug Gauge Do?

Thread plug gauges are used to check the thread size and number of threads. This is done before the machining or assembly work or even before applying the sealant on a machined hole.

The purpose of thread plug gauges is to ensure that the correct size and number of threads are used for the application. For example, if you were making an oil filter housing and wanted to use a 13 mm-diameter internal thread, you would need a 13 mm-diameter internal thread gauge.

Thread plug gauges can be made from various materials, including brass, stainless steel and plastic. They can also be custom-made to your specifications to match your application's requirements.

Top Applications of Thread Plug Gages

1. Threading - Thread plug gages are used to check the thread length, pitch and diameter of screw threads. They are also used to check the setup length and chamfer of screws. These gauges are used in various industries, such as automotive, electronics, aerospace, etc. These gauges have an adjustable stem that can be rotated in different directions multiple times to ensure they have reached their limits.

2. Thread Forming - Thread forming is manufacturing precision parts by machining or extruding. The main purpose of this process is to create complex shapes by creating a series of parallel grooves on a mandrel or bar, which is then cut into parts using a cutting tool.

3. Part Inspection - Thread plug gages are used for inspecting parts made from metal materials like steel or aluminium due to their accuracy and precision.

4. Forged parts inspection - Thread plug gages are used for inspecting forging tools, dies and punches by measuring the diameter of the forged part. It is a significant part of any forging process as it helps control the centring, heat treatment and other variables so that you can produce quality parts with minimal defects.

In The End

The best way to find the right thread plug gauge manufacturer is to look at their website. There should be a section on their site listing all of the products and services they offer for sale. You may also want to contact them directly by email or phone and ask them if they have any new products or services that they would like to sell you.
