Tow bar tongues

Purchased a tow bar tongue from Repco, box tube that slots into Hayman Reese tow bar secured by pin & R clip,
Mate reversed his ute on to it, busted a reverse light & a very slight ding, the tongue on my hitch appeared bent????? Very odd, should be capable of carrying a road train... Well you know what I mean, on closer inspection & to my horror I found it had cracked, I returned the item to Repco yesterday, it will be investigated by their warranty claims people. Inquired as to where these items are made... Yep you guessed right, China. Mmmmm
I can't overstate the safety issues here!!!! & to be fair to Repco as they only found out about it yesterday I won't do a beat up on them but, I feel some info should be out there ASAP, so if anyone has purchased the same item from Repco just be aware that you may have a potential problem.
The item is readily identifiable from the indentation of the hex from the tow ball into the tongue on both sides, & that is I belive where the problem lies, they would be heated red hot to make the forming process easier, & they would be pumping them out like a sausage machine, can't have the process slowed down waiting for the little critters to cool down so they quench them... Any one who knows a little bit of metallurgy knows that's ok if done properly!! If not it can make the steel very brittle, which is what I think has happened here.
It might just be a one off case!!! Lets hope so, will post the outcome. Cheers... Tommy
