39mm Round Galvanised U-Bolt Incl Gal Nylocks
39mm round galvanised U-bolt made by Couplemate. We manufacture our own galvanised U bolts.
Rolled threads with gal flat washer and galvanised nylocks. Thread length is 60mm.
How do I calculate the correct length, measure
- Spring width plus
- Axle Pad 8mm plus
- Axle width plus
- Nylock plus
Ensure the thread passes through the nylon in the nut. The nylon captive insert is the key to locking a Nylock nut onto a thread.
Removing the Nylock nut weakens the nylon insert upon reuse.
How to Measure U-bolts (example)
It is important you retighten U-bolts approximately 200lkms after installation due to steels ability to stretch a little under load.
Furthermore, we stress-tested these u -bolts during manufacture and batch test until destruction.
Destruction loads exceed 17,000kg for 1/2 inch galvanised U-bolts.
Finally, 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 750kg axles is 750kg with U-bolt rating @ 1500kg.
The humble U-bolt is a major cause of caravan accidents.
