3/8 inch Diameter Semi-Round U-Bolt

• Pricing includes Extra Deep Nuts and Hardened Thick U-bolt Washers
• Custom bent U-bolts are non-returnable.

Measure your U-bolt using the image above to to get your pricing.

• “C” = Inside Width    (measure inside width)
• “L” = Inside Length   (measure from the highest point inside to the bottom of the leg of U-bolt)
  • Note that the “L” measurement (length) may be slightly longer and is not exact depending on total rod length. The reason the “L” measurement may be longer (up to 3/4 of an inch) is we add “C” and “L x 2” measurements to get the total material length which is made in even lengths, 22, 28, 38 etc. We do not want your U-bolt to be shorter than the length you ordered.
• “T” = Approximate Thread Length is calculated by multiplying 2 X “L” plus “C” (which equals the overall length of rod material before bending)
  • Approximate thread lengths are predetermined and are listed below;
    • (Total rod length = Thread length on each leg)
      • 8″   to 20″ = 2″-3″
      • 22″ to 30″ = 4″
      • 32″ to 48″ = 6″

These 3/8 inch Diameter Semi-Round U-Bolts are for suspension, leaf spring and body mounting primarily, but have hundreds of other uses. We bend our own U-bolts on a hydraulic bender cold so the grain of the metal stays oriented in the right direction for maximum strength.

The only thread pitch we use are SAE (fine) and are manufactured by rolling a rod between dies creating threads for maximum strength. This makes the non-threaded part of the stock slightly smaller in diameter than the diameter of the threads and are not thread-able beyond the way they are.

Small diameter U-bolts (especially 1/2 diameter and smaller) are more susceptible to measuring slightly wider due to the spring-like nature of the steel, but U-bolts, when properly torqued will typically conform to the shape of the item it is fitting over.

This product is not for ornamental use and is designed to be torqued.
