How to Measure U-bolts (example right image)

Why should I check and re-tighten u-bolts?

Firstly, you must retighten U-bolts approx 200kms after installation due to steels 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.

We stress-tested these u-bolts during manufacture and batch test until destruction.

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.

This article is the catastrophic result of the incorrect tightening of the u-bolt on a truck chassis.
