How to Measure U bolts (example)

It is essential you retighten u-bolts approx 200lkms after installation due to steels ability to stretch a little 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.

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 60mm Round axles is 3000kg with u-bolt rating @ 1500kg.

Vibration fatigue affects trailer u-bolts. Retightening is essential.
