50mm Square Galvanised U Bolt Kit | Gal Nylocks | Gal Washers

50mm square galvanised U bolt includes galvanise nylocks and washers.

Further, the 50mm square galvanised U bolt have rolled threads as opposed to cut threads. Additionally,

  • the thread length is 60mm.
  • the thread size is 1/2″ BSW.

U-Bolt kits with clamps are found here.

Four elements uniquely define any U-bolt:

  1. Material type (for example bright zinc-plated mild steel or galvanised)
  2. Thread dimensions (for example 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.

Accidents can be caused by loose u bolts.

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 max rating of 750kg axles is 750kg with ubolt rating @ 1500kg.

Vibration fatigue can loosen u-bolts if not re-tightened after 300 km. Very good article on vibration fatigue here.
