Trusted by engineers across multiple sectors, this U-bolt is manufactured from high-grade carbon steel, offering exceptional tensile strength and durability for critical applications. Featuring an inside width (A) of 3.62 inches and an inside length (B) of 4.91 inches, it is designed to accommodate standard 3-inch nominal pipe sizes. The 1/2"-13 UNC coarse thread provides robust and secure clamping force, suitable for medium-duty to heavy-duty pipe support, conduit mounting, and general structural fastening where vibration and stress are significant factors.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Position the U-bolt around the pipe, ensuring it is centered. 2. Place the included steel backing plate (if provided) against the pipe. 3. Insert the threaded legs of the U-bolt through the mounting surface or bracket. 4. Secure the U-bolt by threading the accompanying nuts onto the bolts, tightening evenly to achieve the required clamping force. Ensure nuts are fully engaged on the threads.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the nuts, which can deform the pipe or bracket. | Use a torque wrench to tighten nuts to the manufacturer's recommended torque specifications for the specific application and material. |
| Using the wrong size U-bolt for the pipe diameter, leading to a loose or insecure fit. | Always verify the pipe's nominal and actual outside diameter against the U-bolt's inside dimensions (width and length) before installation. |
| Exposing the carbon steel U-bolt to corrosive environments without proper protection. | Apply a suitable anti-corrosion coating or select a corrosion-resistant material (e.g., stainless steel or galvanized) if the installation environment is humid or corrosive. |
