DIN3570 Grade 4.8/8.8/10.9 Galvanized U Bolt
DIN 3570 U-Bolt Specification
Product Description
A U-bolt is a type of bolt that resembles the letter "U" with threaded ends on both sides. These bolts are commonly used to support pipes, tubing, and other cylindrical structures in various industries. Historically, U-bolts were often specified based on the nominal bore of the pipe they supported, which could be confusing since the actual dimensions of the bolt may not match the nominal size. For example, a "40 Nominal Bore U-bolt" might be requested by engineers, but the term refers more to the internal diameter of the pipe rather than the physical size of the U-bolt itself. As U-bolts have become more widely used across different applications, including clamping round bars and tubes, a more standardized measurement system has been adopted to make it easier for users to select the right product. Today, U-bolts are available in a range of sizes and specifications, making them suitable for use in construction, automotive, industrial, and mechanical applications. Whether you need a standard or custom-made U-bolt, there are options available to meet your specific requirements. With a variety of materials, finishes, and grades, these fasteners offer durability, strength, and versatility for a wide range of projects.
