First,I would like to say that the screws in the picture dont match what
GW sends you. WG sends a screw at least 1 size smaller in diameter, but
much longer.About 1/8 inch thick threads.Maybe less. Those screws in your
picture show nice tapered heads. the screws provided dont fit the tapers
of the luggage rack tie downs,properly.They can be found Wayyyyyyyyyy down
inside the tapers, when fastened.

Look on the internet for footman loops ,tie dwons marine stainless
steel ,ect. I have seen this identical tie down some place else before,
but dont remember where.

I would like to make up some  OEM style in stainless steel someday.
