Four elements uniquely define any U-bolt, they are:

  1. Material type (for example bright zinc-plated mild steel or galvanised)
  2. Thread dimensions (for standard 1/2″ )
  3. Inside diameter (for example 50 mm – the distance between the legs)
  4. Inside height (for example 125 mm)

Mild steel stretches under load. It is essential you re-tighten u-bolts approx 200 km after installation.u-bolt testing

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 of 1500kg.

Vibration fatigue can loosen u-bolts if not re-tightened after 300 km.

Excellent article on vibration fatigue here.

The 250mm U-Bolt Kit is 250mm when measured from the tip of the thread to the underside of the top.

The kit comprises

  • 1 x ElectroGal U-Bolt
  • 2 x ElectroGal Washers
  • Nylocks x 2
