That is exactly the type that Schwinn used on their first generation of
giraffes.  It has two sets of threads with one of them threaded in the
reverse direction.  It's not guaranteed not to unscrew on a giraffe. 
Welding the cog to the hub is the only way to be absolutely sure that it
will not slip.

Schwinn's second generation of giraffes used bolts similar to lug nuts
to secure the cog to the hub.  This style of hub will not slip and does
not need to be welded.  Unfortunately Schwinn is no longer making
giraffes and you can no longer get that hub.

I was hopeful (and remain hopeful) that Torker would design a better
giraffe hub that will not slip.  We need one because all of the giraffe
hubs available right now are the threaded track style hub.  We need one
of the giraffe manufacturers to manufacture a hub that will not slip. 
Something with a bolt on cog or splined cog or something else that will
prevent the cog from ever coming loose while riding.
