Thread measurement instructions
This text provides a comprehensive guide to the basics of thread measurement and its importance in different environments. In addition, we offer a downloadable thread chart that helps you understand and identify different types of threads.
Use of a caliper
A caliper is one of the most common tools used to measure the diameter of a thread. It is easy to use and provides sufficient accuracy for most applications. By measuring the outside or inside diameter of the thread, you can get a first idea of the size and type of thread.
The meaning of spiral comb
When the diameter is determined with the push gauge, the pitch of the thread is measured with the thread comb. A thread comb is a special tool with several saw edges of different sizes, which can be used to precisely measure the pitch of the thread. This information is necessary when you want to determine the exact type of thread, such as 10×1, which means 10 mm thread diameter with 1 mm pitch.
Different thread types: inch and metric threads
When choosing a thread, it is important to know in which country and for what purpose the device is used. For example, metric threads are most commonly used in Europe, while inch sizing is preferred in the United States. This information is essential so that the parts fit together without problems.
Special threads for different uses
Taper thread (NPT) is an example of a special thread used primarily in the United States that provides a tight connection in compressed air and water piping systems. Knowing what type of thread is used in each country will help you choose the right type for different applications.
Utilization of spiral tables
Thread tables are an excellent tool that facilitates the identification and selection of threads. They provide a quick overview of the dimensions and properties of different threads, so it is easy for the user to quickly find the thread that suits their needs.
Downloadable spiral table
From our website you can find a downloadable thread chart for free that covers the most common threads in use. Designed to be easy to use and informative, this chart provides a quick way to make sure you're choosing the right thread.
Measuring and identifying threads is an important skill in many technical fields. Choosing and using the right thread ensures the devices' flawless operation and long service life. We hope this blog post and our downloadable thread chart will help you understand the basics of thread measurement and help you choose the right thread for your needs.
