Important Information

5/8"Our UBolts are Fine Thread (SAE 5/8-18). When ordering your UBolt, the diameter you order will be the diameter of the threads. The un-threaded portion of the UBolt is approx 1/64 to 3/64 smaller in diameter.

3 1/2"Inside Width (we bend around a die this size). Some ubolts will measure slightly wider due to the rod material. When you properly torque the ubolt, normally they will tighten in to the width chosen. U-Bolts must be tightened and torqued properly at max torque of 177 ft lbs using a cross pattern sequence. View the torque guide here

Selected Inside Length. This measurement can vary by 1/4" to 1/2".
Thread Length on U-Bolts are generally 1 1/2"- 3", or more depending on the length of the rod. These rods come pre-threaded so we are unable to do custom thread lengths.
If you need an exact thread length, please call us toll-free at 1-877-HITCH-IT (448-2448)

5/8" U-Bolts are Grade 8 Steel, Right Hand Thread with No Finish and Basic Mfg Oil. These are Fine Thread Only (SAE 5/8-18). Nuts, Washers, and Plates Sold Separately.

If you would like a quote on Stainless Steel, Yellow or Clear Zinc, or Hot Dipped Galvanized please call us at 1-877-448-2448. For Stainless Steel, Zinc Coated, or Hot Dipped Galvanized orders, there is a 50 piece minimum order. Please note that Hot Dipped Galvanized is only available on Low Carbon Steel UBolt material.

Please note all ubolts will rust without proper coating. Even then, this does not guarantee that they will not rust. This depends on the amount of time they will be used and the environment they will be used in.
