DIN 3570 U bolts

DIN 3570 U bolts

As a premier factory and manufacturer in China, we provide high-quality DIN 3570 U-bolts, the definitive solution for industrial pipe and tube fastening. These robust fasteners are shaped like the letter “U” with machine threads on both ends. Designed to be used with nuts and washers, they provide a secure and stable clamp around pipes, conduits, rods, and other cylindrical components. Manufactured from durable carbon steel with protective coatings or corrosion-resistant stainless steel, our DIN 3570 U-bolts are engineered for reliability in demanding sectors such as construction, chemical engineering, machinery, and pipeline installation.

Product Details

Our DIN 3570 U-bolts are meticulously manufactured to deliver consistent performance and a secure fit for a wide range of applications.

  • DIN 3570 Standard for Pipe Sizing: These U-bolts are produced in compliance with the DIN 3570 standard, which specifies dimensions based on the nominal pipe size they are intended to secure. This ensures a precise fit and interchangeability for standard metric and inch pipe sizes, providing a reliable and consistent clamping solution.
  • U-Shaped Design for Secure Clamping: The distinctive U-shape is designed to wrap around the circumference of a pipe or tube. When the two threaded ends are inserted through mounting holes and tightened with nuts, they create a strong, evenly distributed clamping force that firmly holds the component in place, preventing movement and vibration.
  • Material and Finish Options:
    • Carbon Steel: For high-strength applications, we offer U-bolts made from carbon steel in various grades (e.g., 4.8, 8.8). These are typically coated for corrosion protection. White Zinc Plating is a standard finish offering good rust resistance for general and indoor use. For more demanding outdoor or corrosive environments, a Hot-Dip Galvanized (HDG) finish can be provided.
    • Stainless Steel (A2/304, A4/316): For applications requiring maximum corrosion resistance, such as in marine, chemical, or food processing environments, we offer U-bolts made from A2 (304) or A4 (316) stainless steel.
  • Dual Threaded Ends: Each U-bolt features two threaded legs, allowing for secure fastening with two nuts (and washers). This dual-point connection provides superior stability and holding power compared to single-point fasteners.

Product Features

Our DIN 3570 U-bolts are engineered with features that guarantee strength, durability, and ease of use.

  • Robust Clamping Force: The U-shape and dual-nut design provide a powerful and balanced grip, securely immobilizing pipes and preventing slippage or rotation.
  • Excellent Corrosion Resistance: With options for zinc plating, hot-dip galvanizing, or solid stainless steel construction, our U-bolts are built to withstand rust and corrosion in various environments.
  • Standardized for Perfect Fit: Adherence to the DIN 3570 standard ensures that the U-bolt dimensions are perfectly matched to standard pipe sizes, simplifying selection and guaranteeing a proper fit.
  • High Strength and Durability: Available in high-strength carbon steel grades, these U-bolts can handle heavy loads and provide long-lasting structural support.
  • Versatile Application: Ideal for more than just pipes, these U-bolts are also used to secure cables, conduits, structural framing, and even as an anchor point in concrete.

Product Applications

DIN 3570 U-bolts are a fundamental component in a multitude of industrial, commercial, and residential applications.

  • Pipe and Conduit Support: Their primary use is to support and restrain pipes for plumbing, HVAC, process piping, and electrical conduit systems, securing them to walls, ceilings, or structural beams.
  • Structural Connections: Used in construction to fasten round or square posts, beams, and framing members to other surfaces.
  • Automotive and Transportation: Commonly used in vehicle suspension systems (e.g., to attach axles to leaf springs), secure exhaust pipes, and mount components to vehicle frames.
  • Marine and Coastal Installations: Stainless steel U-bolts are essential for securing rigging, railings, and equipment on boats and docks due to their superior resistance to saltwater corrosion.
  • Telecommunications: Used for mounting antennas, satellite dishes, and cabling to masts and towers.
