Some of the longer u-bolt lengths are difficult to locate. Couplemate carries a good stock of these longer u-bolts because we know you want them in a hurry. How do I calculate the correct length? •Spring width plus •Axle Pad 8mm plus •Axle width plus •Nylock plus Why should I check and re-tighten u-bolts? Firstly, you must retighten U-bolts approx 200kms after installation due to steels ability to stretch a little under load. U-Bolts generally fail due to hydrogen embrittlement. Hydrogen embrittlement occurs during bending and galvanising. At Couplemate we have a new process that removes hydrogen embrittlement to produce ST class U-bolts. We stress-tested these u-bolts during manufacture and batch test until destruction. What is the rating for u-bolts? Destruction loads exceed 17,000kg for 1/2 inch galvanised u-bolts. 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 60mm Round axles is 3000kg with a u-bolt rating of 1500kg.
