Big B,
Yeah, we've even struck these sorts of fittings over here in New Zealand.
Cheap junk, is all I can call them.
If the end of the threaded rod is out of wack, there is a simple way to fix that:
  • Get 2 nuts that are the same thread as the rod and screw them onto the rod.
  • Secure the rod and nuts.
  • Get a 4" grinder with a fine grinding wheel and grind it flat.
  • When finished, screw the nuts off of each end, this will cut a new thread on the ends that the grinder took off.


I realise this is a lot of un-necessary mucking about, to correct a manufacturing fault, but if you want things to fit correctly, you should do this.

Just my $0.02 worth.
