Thread Chart (Metric Threads) – Major and Minor Diameters

When it comes to thread size chart, there are a number of different factors you will need to keep in mind. You’ll want to make sure that the thread you are using is of the right diameter, and that the diameter is in accordance with the Unified Thread Standard (UTS). In addition, you’ll want to make sure that the thread is straight, tapered, or metric.


A straight thread is a type of pipe connection that maintains the same diameter throughout its entire length. There are several different types of threads. This article will highlight some of the main differences. One of the most important aspects of a thread is the pitch. The pitch is the distance between two adjacent threads. It can be deciphered by using a pitch gage or a thread gauge.

Another way to figure out the pitch is by calculating the total number of threads per inch. The results will narrow down the possibilities of what thread form to use. The American National Standard Pipe Thread is a popular option in the United States. They are also known as ISO Taper or NPT. These threads are used for loose fitting mechanical joints with locknuts.


Tapered threads are made of a smaller diameter at the tip to help the connection transmit more force. They are self-sealing and are a popular choice for pipe connections. A tapered thread size chart can be used to identify the size of a tapered thread.

The first step to identify a tapered thread is to measure the outer diameter of the fitting. You can use a caliper to check the thread’s diameter. If you can’t do this, you can use the pitch gauge to measure the distance between the crests of the threads. This will be used to determine the pitch of a thread. Metric tapered threads are designed with a fine taper. This ensures the best force transmission. They are available in a straight or parallel version. Both types are used in pipe connections.


The Denier thread size chart is a helpful way to determine the correct thread size. It is the industry standard for measuring threads. However, it is not always a good indicator of thread thickness. A denier thread is a measurement of the linear density of a single strand of fiber. There are several common sizes of thread. Several brands also have variations.

There are three main types of thread. These include embroidery thread, mono thread, and polyester thread. Each has its own properties and benefits. Embroidery thread is typically labeled in denier. This system is used to measure strength. Using the Denier thread size chart, you can decide if it is the right thread for your fly tying project. Uni-Products is a Canadian company that sells a variety of threads. They sell nylon, polyester, and Kevlar. Their threads are available in a variety of colors.

Unified Thread Standard (UTS)

The Unified Thread Standard (UTS) is the standard threaded fastener for bolts, nuts, and screw threads. It was developed in 1949. This is the main standard for threaded fasteners in the United States, Canada, and the United Kingdom. UTS threads are formed from a V-shaped thread with flanks at a 60-degree angle. These threads are available in many sizes from 3/8 inch to 12 inches in diameter.

Some UTS threads can have three Teeth Per Inch (TPI) configurations. A single TPI configuration is referred to as a “gauge” and a two-TPI configuration is referred to as a “ring gauge”. For a better understanding of the UTS, it’s important to understand the basics of threads. These include the major diameter, pitch, and tolerance. Depending on the thread type, a thread will have either a fine, coarse, or extra-fine pitch.


Metric threads are generally classified as fine or coarse. The difference in diameter between fine and coarse is not as great as that between an inch or a millimetre. They also vary in pitch. Fine pitch threads are used where coarse pitch is too tall for the application.

Pitch is a measurement of the distance between the two adjacent threads. There are a number of different pitches from a coarse pitch to a superfine pitch. In general, a fine pitch metric thread is more resistant to vibrations than its coarse counterpart. The metric thread is a symmetric v-shaped thread with a 60 deg flank angle. The major diameter is also known as the male thread diameter. This is often the size of a drill bit.

Last Word

The thread size chart is designed to be a quick reference guide to threads. Threads can be identified by thread type, numbering system, and weight. There are several thread types that include PT, G, and NPTF. You can find more information on threads by visiting Wikipedia. See here https://yijinsolution.com/.
