U shaped bolts have been around for many years. In fact, they perform a number of important tasks in a wide range of commercial and industrial applications today. However, the importance of these bolts is sometimes overlooked as many other technologies are focused upon in the 21st Century. Yet, whether you need off the shelf or custom U bolts for your needs, it’s important to understand, they are not all created equal. This kind of bolt is an essential support for many applications and choosing the right ones can make a big difference in your business. Here are some tips for choosing the best products.
Threading Method
Most manufacturers are using less expensive roll threading methods, instead of thread cutting. This lowers the price while creating stronger threads. If you have concerns about thread stripping, rolled threads are the best choice.
Hot Forged or Cold Worked?
Most bolts are cold worked but some companies still produced hot forged products. In most cases, you’ll want cold forged metal but if you are looking for custom U bolts, it’s best to know all the options.
Hot Forging
In order to forge steel parts, the metal must be heated to over 1000 degrees Celsius. This creates fairly accurate parts and makes them easier to work with. Also, the metal will not work harden easily. However, it can create inconsistent grain structures and must be done in a controlled atmosphere to limit contamination.
Cold Forging
This process is done at normal operating temperatures. The metal is formed as it is forced through a die. This does not usually require finishing, which helps to keep costs down. There is little deformation and many parts can be created within a short amount of time.
Here is some advice: Go with a trusted source for stock and custom U bolts. Choose rolled thread and cold worked for best results.
