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.
