80mm Square Galvanised U Bolt - Nylocks - Washer
80mm Square Galvanised U-Bolt made by Couplemate. We manufacture it own galvanised U-bolts. U-bolts can be supplied bulk with nuts and washers on the threads in boxes of 50.
Rolled threads with gal flat washer + gal nylock. Thread length is 60mm.
How do I calculate the correct length, measure
- Spring width plus
- Axle Pad 8mm plus
- Axle width plus
- Nylock plus
- 5mm thread through nylock
For example, 3 leaf slipper on 39mm Round axle is
18mm Spring + 8mm Axle spacer + 39mm axle + Nylock 15mm + 5mm
Total U-bolt minimum length = 120mm
How to Measure U-bolts (example)
It is important you retighten U bolts approx 200lkms after installation due to steels ability to stretch a little under load.
U bolts are a major cause of caravan wheel alignment problems.
U bolts generally fail due to hydrogen embrittlement. Hydrogen embrittlement occurs during bending and galvanising. At Couplemate we have an extra process that removes hydrogen embrittlement to produce st class u bolts.
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.
Our ubolts are derated to 375kg each or 1500kg per set of 4 or enough ubolts to suit a single axle.
The max rating of 60mm Round axles is 3000kg with ubolt rating @ 1500kg.
