Precision-manufactured to tight tolerances, this U-bolt features an inside width (A) of 3.90 inches and an inside length (B) of 7.27 inches, specifically designed to accommodate 4-inch nominal pipe. Constructed from premium 316 stainless steel, it offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, even in chloride-rich environments such as marine, chemical processing, and food/beverage industries. The 1/2"-13 UNC thread size allows for secure fastening with standard nuts and washers, providing a dependable solution for structural support and pipe anchoring.
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 rests securely on the supporting structure. 2. Thread the nuts onto the U-bolt legs, hand-tightening initially. 3. Tighten the nuts alternately and evenly to achieve the required clamping force, as specified by structural or piping codes.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect U-bolt size for the pipe nominal diameter. | Always verify the inside width (A) of the U-bolt matches the outer diameter of the pipe being secured, accounting for any insulation or coatings. |
| Insufficient or uneven tightening of nuts. | Ensure nuts are tightened to the specified torque values and that pressure is applied evenly across both legs of the U-bolt to prevent pipe distortion or structural stress. |
