39mm Round Galvanised U-Bolt Incl Gal Nylocks 39mm round galvanised U-bolt made by Couplemate. Also known as 40mm round u bolts. Rolled threads with gal flat washer and galvanised nylocks. The thread length is 60mm. How do I calculate the correct size? 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. How to Measure U-bolts Measure u-bolts from the inside of the U-bolt to the tip of the thread. It would be best to retighten U-bolts approximately 200lkms after installation due to steel's ability to stretch a little under load. Furthermore, we stress-tested u -bolts during manufacture and batch test 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 U-bolt rating @ 1500kg. The humble U-bolt is a major cause of caravan accidents. Weight:0.5 kg Dimensions:10 × 6 × 6 cm
