Four elements uniquely define any U-bolt, they are:
- Material type (for example bright zinc-plated mild steel or galvanised)
- Thread dimensions (for standard 1/2″ )
- Inside diameter (for example 50 mm – the distance between the legs)
- Inside height (for example 125 mm)
Loose u-bolts cause accidents
Catastrophic consequences on a truck chassis were the result of incorrect u-bolt tightening.
Furthermore, u-bolts are stress-tested during manufacture and batch tested until destruction.
Destruction loads exceed 17,000kg for 1/2 inch galvanised u-bolts.
Finally, u-bolts are derated to 375kg each or 1500kg per set of 4 or enough u-bolts to suit a single axle.
The maximum rating of 750kg light trailer axles is 750kg with a u-bolt rating @ 1500kg.
Vibration fatigue can loosen u-bolts if not re-tightened after 300 km.
