How to Measure U-bolts (example right image)
Why should I check and re-tighten U-bolts?
Firstly, you must retighten U-bolts approximately 200kms after installation due to steel's ability to stretch a little under load.
U-bolts generally fail due to hydrogen embrittlement. Hydrogen embrittlement occurs during bending and galvanising. At Couplemate, we have a new process that removes hydrogen embrittlement to produce ST class U-bolts.
What is the rating for u-bolts?
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 a u-bolt rating of 1500kg.
