Roof Rack Mounting Holes

Anyone know if it's okay that the mounting holes in the roof rails are exposed?(photo).
Mine looks exactly like your pictures, i.e. there is no bolt or seal on the threaded hole, thus it can be assumed none is needed.
I believe the threaded hole in question is a "blind hole" that simply ends in solid metal at the bottom. You can test this by running a narrow screwdriver, wire, pencil etc down the hole and seeing if it is indeed blocked. It should not go through the roof metal and will not leak.
