Custom-Bent 7/16″ Square U-Bolts

Our 7/16-inch diameter square U-bolts are custom-bent to your exact specifications. Primarily engineered for suspension, leaf spring, and body mounting, these heavy-duty fasteners are built to be torqued and are not for ornamental use.
We cold-bend our steel U-Bolts on a hydraulic bender to maintain metal grain orientation for maximum strength.

⚠️ Ordering Rules & Pricing

  • Hardware Included: Every price includes Extra Deep Nuts and Hardened Thick U-bolt Washers.
  • How to Price: Select your measurements and the price will be calculated.
  • Non-Returnable: Custom-bent U-bolts are made to order and cannot be returned.

📏 How to Measure Your U-Bolt

Please read these instructions carefully before ordering. Use your product image as a reference:
  • “C” = Inside Width: Measure the exact inside width of the bend.
  • “L” = Inside Length: Measure from the highest point inside to the very bottom of the leg.
  • “T” = Thread Length: Thread lengths are predetermined based on total rod length. (See below Predetermined Approximate Thread Lengths)

💡 Important Length Note: Your delivered “L” measurement may be up to 3/4″ longer than ordered. We calculate total rod length using even numbers (C + (L × 2)) and rounding to the next even length to ensure your U-bolt is never shorter than you need.

🛠️ Fitment & Torque Behavior

  • Spring-Back Notice: Because of the spring-like nature of steel, small-diameter U-bolts (1/2″ and smaller) may measure slightly wider upon arrival.
  • Self-Conforming: When properly torqued, the U-bolt will naturally conform to the shape of the item it fits over.

⚙️ Thread & Rod Specifications

  • Thread Type: We use SAE (fine) threads exclusively.
  • Maximum Strength: Threads are rolled between dies rather than cut for maximum strength.
  • No Re-Threading: The unthreaded stock is slightly smaller in diameter than the threads. They cannot be threaded further by the user.

🔍 Predetermined Approximate Thread Lengths

Use this quick reference chart to find your thread length. If your thread length is a critical measurement, please call us to confirm before ordering.

Total Rod Material Length Thread Length (On Each Leg)
8″ to 20″ 2″ – 3″
22″ to 30″ 3″ – 4″
32″ to 48″ 4″ – 6″

    These custom U Bolts are just what I need for my boat trailer. I could not find the length that I needed elsewhere and at a reasonable price. They arrived quickly and well packaged. I highly recommend Dsuban for custom U Bolts.

    It’s funny; I was going to say the same kind of thing as Tom D. I also used them on my boat trailer. Well made and fit the trailer frame like a glove. I know where I’ll be going the next time I need custom hardware.

    I had an odd size square bend u bolt that I needed for my utility trailer tongue Warn winch mounting plate. Dsuban had what I needed! U Bolts came with washers and hex nuts (Awesome!). Both U Bolts were well made, threads were clean, and overall size was exactly what was promised. I recommend there products, and will purchase from them again! Shipping was fairly quick considering I live in Texas.

      Thank you for the review! Our shipping charges are the actual cost from UPS using a software link to their site. We do not make anything on shipping. We hope you come back for your U-Bolt or other needs.

  15. Mel –

    The U-bolt was exactly as expected. Two suggestions for the future. It was unclear to me how high up the threads go on the turn downs. I would suggest to thread farther up. I ran out of threads on my appliction

    Mel –

  16. JPW –

    Superior product! Threads on bolts cover a large area helping it fit the application and nuts are extra long to help keep from slipping. I purchased these for my 24 gang disc plow and I can tell they are going to work better than factory.
