How to Measure U bolts (example)
It is important you retighten u bolts approx 200lkms after installation due to steels ability to stretch a little under load.
Furthermore, 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.
Finally, our u bolts are derated to 375kg each or 1500kg per set of 4 or enough u bolts to suit a single axle.
The max rating of 750kg axles is 750kg with ubolt rating @ 1500kg.
Vibration fatigue can loosen u-bolts if not re-tightened after 300 km. Very good article on vibration fatigue here.
