Gonna throw in another re this issue ....I have turned down some 12mm nuts just to take off the corners, then I mounted these while attached to the a long bolt into holes in my cross brace so each boss was half in and half out of the thickness of the cross brace tubing, then welded them up top and underneath then when cool I removed the bolt.......so my threaded section does not go all the way through.......does this mean it would fail or would it be enough and if not could I use a long bolt instead with a nyloc on the bottom,
Failing all else I could drill them out and put a full thread length boss in, don't want to do that tho.......any thoughts peeps???
