In the 1960's a friend of mine came up with the typ of screw head in husky man's control box as a joke and called it the "Simpson Head Screw" after struggling with a damaged Phillips head, imagine his surprise decades later when these showed up .

I hope you post the failure point and repair done, photos would be good .
