Rolled threads with gal flat washer + gal nylock. The thread length is 60mm.
Some of the longer u-bolt lengths are difficult to locate. Couplemate carries a good stock of these longer u-bolts because we know you want them in a hurry. You have the choice at checkout to send via Express Post if you wish.
How do I calculate the correct length?
- Spring width plus
- Axle Pad 8mm plus

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.
