My neighbor is an aircraft structure mechanic/engineer with Westjet up here in Canada. I asked him once why pretty much all of the screws on aircraft skins are the dreaded Phillips X-head types. He said that the Phillips design gives "good" (not the best) driver head contact and offers the most strength since relatively little metal is removed from the head to make them. He told me that Roberson heads are relatively weak in comparison with so much metal missing because of the square design. Just saying what I was told. I know that back in the day, all motorcycle cases were pretty much the dreaded Phillips ..... I say dreaded because unless you used an impact driver, you were pretty much guaranteed to mess them up when trying to take the engine cases apart. You could always tell if there had been engine work done, the Phillips heads were messed up.
