Of course you are correct, I was thinking of a previous version that I had abandoned that had the bolt covered. The current version, which you have, uses button head screws instead of socket head screws. I can tell you that I have over 350 of the various SWAT mounts in use. I have not had a single report of a failure unrelated to a crash. I am confident that the mount works based on this fact. If you are unhappy with the design you can express your concerns with Shapeways Customer Service. I am not a Shapeways empoyee so I do not have any sway over Shapeways.
