Thanks, the hole isn't threaded just a plain hole 13mm dia  for M12 or 1/2" bolt. Although an hex hd bolt doesn't normally fit too good, can't get the ring spanner or socket in    so I tend to use a cap head/ button head.

It there is access one can use a nut, otherwise a 12mm plate with a tapped hole is welded on.

The reason I went for the single bolt hole is because the plate size on the castor is wider than the 63.5mm sq tubing, I could have welded a plate on the bottom of the tubing and then I'll keep catching my ankle on it
