The Stainless Steel U-Bolt (Round Bend) is the definitive fastening solution for securing pipes, conduits, and cables to structural beams. Shaped like the letter “U” with machine threads on both legs, our Stainless Steel U-Bolt is engineered to wrap around cylindrical objects, providing a secure, vibration-resistant grip. Whether you are outfitting a yacht or installing industrial plumbing, these bolts offer superior corrosion resistance compared to galvanized alternatives.
Product Overview: Manufactured from premium Stainless Steel A4 (316) for marine environments or A2 (304) for general use, our U-Bolts are available in a wide range of sizes to fit standard pipe schedules (DN15 to DN500). They are often supplied with matching hex nuts and a flat plate (backing plate) upon request.

Engineering Insight: How to Measure a U-Bolt
Ordering the wrong size Stainless Steel U-Bolt is a common mistake. Here is how to get it right:
- Inner Width (ID): This is the most critical dimension. It is the distance between the legs. It should be slightly larger than the outside diameter (OD) of the pipe you are clamping.
- Leg Length: The total length of the leg. Ensure it is long enough to pass through your mounting bracket and still have room for the nuts and washers.
- Nominal Bore (NB) Confusion: A “2-inch pipe” actually has an OD of about 60.3mm (2.375 inches). Do not buy a U-bolt with 2-inch (50mm) width for a 2-inch pipe; it won’t fit! Always check the pipe’s Outer Diameter.
For more details on pipe support standards, please refer to the U-bolt entry on Wikipedia.
Applications
- Marine Rigging: Securing stanchions and deck hardware on boats.
- Plumbing: Supporting fluid and gas pipes in food processing plants (where hygiene and rust-proofing are mandatory).
- Automotive: Fastening leaf springs on trailers and 4×4 vehicles (usually requires high-tensile steel, check specs).
Frequently Asked Questions (FAQ)
Q: Do these come with nuts?
A: Our standard U-bolts are sold as the bolt only. However, we offer “U-Bolt Kits” which include 2 hex nuts and 2 flat washers. Please specify if you need the full assembly.
Q: Can I get a custom shape?
A: Yes. Handan Bolt specializes in custom bending. We can manufacture Square Bend (for box sections) or V-Bolts based on your drawings.
Need Custom U-Bolts?
Handan Bolt manufactures thousands of Stainless Steel U-Bolts monthly. We can customize the leg length, thread length, and bend radius to your exact project requirements.
