Description
63mm Square Galvanised U-Bolts
63mm Square Galvanised U-Bolts include galvanised nylocks and washers.
All 63mm square galvanised u-bolts have rolled 1/2″ threads with gal flat washer + gal nylock. Thread length is 60mm.
It is important you re-tighten u-bolts approx 200 km after installation due to steels ability to stretch a little under load.
We stress-tested these u-bolts during manufacture and batch test until destruction.
Break loads exceed 17t for 1/2 inch galvanised u-bolts.
Our u-bolts are de-rated to 375kg each or 1.5t per set of 4 or enough u-bolts to suit a single axle.
The max rating of 60mm Round axles is 3t with u-bolt rating @ 1.5t.
Read why u-bolts could be the major cause of accidents.
This article is the catastrophic result of the incorrect tightening of u-bolt on a truck chassis.
