A proven choice for industrial professionals, this U-bolt is manufactured from premium 316 stainless steel, offering exceptional resistance to pitting and crevice corrosion, particularly in chloride-rich environments. With an inside width (A) of 4.47 inches and an inside length (B) of 4.38 inches, it is precisely engineered to accommodate standard 3-inch nominal pipe dimensions. The 1/2"-13 UNC threading ensures robust fastening capabilities, making it ideal for applications requiring high integrity and longevity in marine, chemical processing, and offshore environments.
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 3" pipe, ensuring even contact with the pipe surface. 2. Thread the nuts onto the U-bolt legs, hand-tightening initially. 3. Using appropriate wrenches, tighten the nuts alternately and evenly to achieve the specified clamping force, ensuring the pipe is securely held without deformation.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the U-bolt, which can deform the pipe. | Tighten nuts alternately and gradually until snug, avoiding excessive force. |
| Using the wrong size U-bolt for the pipe diameter. | Always verify the inside dimensions of the U-bolt against the pipe's outer diameter and standard nominal pipe size. |
