The locking nut is stainless steel and the bracket is drop forged
aluminium, so it's quite tough, and the weld is done on two or three
faces of the hex where it touches the bracket. The whole thing seems to
melt together quite nicely and leaves a strong bond so the nut can't be
un-screwed. They work, and we like them.

It can't be a weld obviously since that can only be between identical
metal.

But this sounds interesting. Some form of 'braze' that works on stainless
but doesn't melt ally?
