What is the Minimum Bend Radius of U Bolt?

The different steel U Bolts are used in different application perspectives. The different types help achieve different tasks. The U bolt is used in applications where the nuts are fastened on the same side of the surface but the bolt has to connect through different components. As a leading U Bolt manufacturer in India, Rolex Metal Distributors manufactures the different types. The bending radius of the U bolt is considered critical. There are different types such as the square bend U bolt. The minimum bending radius is twice the diameter of the bent rod or bolt.

Why Stainless Steel U Bolt should be formed after the threads are rolled?

As one of the leading Stainless Steel U Bolt manufacturers we produce the bolts in different grades of the material. There are 304, 316 and other types of stainless steel materials used for the production. The 316 Stainless Steel Square U Bolts are formed after the threads are rolled on them. The thread rolling reshapes the bolt with threads. To make sure that the threads are in place and strengthened, the forming operation takes place after threading. If the 304 Stainless Steel U Bolts are formed before threading, the threads might crack while rolling.Also, the newly made threads would not be stronger as the deformed surface is not formed.

Why is chamfering done on U bolts?

The Square Bend SS U-Bolts and other types have to stay in place so that they are chamfered. The operation creates a furrow or bevel on the end of the bolts and keeps the bolt threads intact while allowing for the nuts to enter the threaded area. There are different types such as the Stainless Steel Round U Bolt which are the most commonly used. The square U bolts are less common but are used in specific application types. Please feel free to contact us for the different types such as the Stainless Steel V Bolts and their prices.
