How to Measure U-bolts (example)
It would be best to retighten u-bolts approximately 200 km after installation because the steel tends to stretch slightly under load.
We stress-tested these u-bolts during manufacture and batch test until destruction.
Destruction loads exceed 17,000kg for 1/2-inch galvanised U-bolts.
The max rating of 60mm Round axles is 3000kg with a u-bolt rating of 1500kg.
Vibration fatigue affects trailer U-bolts. Retightening is essential.
