Metal fasteners are an integral part of many construction and industrial processes. They provide the necessary strength and durability to hold the components together, ensuring safety and reliability. But how can you be sure that the metal fasteners you are using are up to par? That’s where a tensile test comes in. The Presto tensile strength tester is used to test the tensile based on the Constant Rate of Traverse (CRT) principle. This easy-to-use high-quality lab testing equipment is equipped with special case-hardened lead screws for stability and durability. It comes with double column rugged structure and safety limit switches that will provide overtravel safety. In this blog post, we will discuss why it is important to perform a tensile test on metal fasteners. We will also discuss how Presto digital tensile strength tester is helpful in testing the tensile properties of metals. So, let us get started!

What is a tensile test and why it should be performed on metal fasteners?

A tensile test is a type of mechanical test that is used to determine the strength and ductility of a material. This test is performed by applying a force to a sample of the material until it breaks. The results of the test can then be used to calculate the yield strength, ultimate strength, and elongation of the material.

A tensile test is performed on metal fasteners to determine their strength and ductility. This information is used to select the appropriate fastener for a particular application. Presto offers a high-quality tensile strength tester that has specially designed gripper jaws for holding fragile samples.

This quality lab testing instrument has been designed with advanced features that will help the manufacturers in conducting tensile strength tests and ensure that quality products will be delivered.

Now, let us discuss brief information about Presto tensile strength tester and how it is helpful in determining the tensile test on materials.

You can also read about what happens when the material will be subjected to a tensile test.

All about Presto tensile strength tester

Tensile testing is an important part of the fastener manufacturing process. It allows manufacturers to measure the tensile strength and other mechanical properties of their products in order to ensure that they are suitable for their intended applications. By performing this test, manufacturers can produce high-quality metal fasteners that meet industry standards and customer expectations.

Presto being the leading manufacturer of tensile strength testers has designed high-quality testing equipment known as a digital tensile tester.

Now, let us focus on the easy steps to perform tensile tests on metals.

Easy-to-follow steps for performing tensile tests on metals

To operate this machine accurately, you need to prepare the sample accurately. For this, you can read more about the steps of preparing the sample with a tensile strength tester. When the sample will be prepared, then you can commence the tests accurately.

For this, follow the steps mentioned below.

Set the peak load indicator value to zero and turn the rotary switch to the down direction.
This will move the lower grip in a lower direction.
Once the movement of the lower grip is in the lower direction, there will be an increase in the values shown on the load indicator.
Now turn the rotary switch to the off position after the specimen has been fractured.
Once the machine stops, the display showing the load will return to zero and the elongation display will freeze.
Press the Memory switch on the load indicator to show the peak value.
Note down the values displayed on the load indicator.

In this way, you can easily test the tensile strength of the materials.
