How to Measure U-bolts (example)

Replacement U Bolt Kit for Jockey Wheel (U3S3)

It is important you retighten U bolts approx 200lkms after installation due to steels ability to stretch a little under load.

U bolts are a major cause of caravan wheel alignment problems.

U bolts generally fail due to hydrogen embrittlement. Hydrogen embrittlement occurs during bending and galvanising. At Couplemate we have an extra process that removes hydrogen embrittlement to produce st class u bolts.

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 ubolts are derated to 375kg each or 1500kg per set of 4 or enough ubolts to suit a single axle.

The max rating of 60mm Round axles is 3000kg with ubolt rating @ 1500kg.
