DIN3570 Grade 4.8/8.8/10.9 Galvanized U Bolt
DIN 3570 U-Bolt Specifications
Product Description
A U-bolt is a bolt shaped like the letter "U" with threads on both ends. It is commonly used to support pipework, where fluids or gases flow through. Historically, U-bolts were described by the size of the pipe they supported, such as a "40 Nominal Bore U-bolt." However, this measurement was more about the internal diameter of the pipe rather than the actual dimensions of the U-bolt itself. With the increasing use of U-bolts in various industries beyond piping, a more practical and universal measurement system has been adopted. Now, U-bolts are typically measured based on the diameter of the tubing or round bar they are designed to clamp. This makes it easier for users from different backgrounds to understand and apply the right size for their needs. Whether you're working on machinery, construction, or general industrial applications, our U-bolts offer reliable performance, high strength, and a variety of finish options to suit your requirements. We also provide free samples for standard fasteners and customized solutions upon request.
