Cannot recognize this at all. In fact, Torx-screws are the only door-mounting[0] screws I have ever been able to screw out rather than cut.
[0]: Where I live (Denmark) doors and windows are these days mounted with an 8 mm hard steel screw directly into a slightly undersized hole in the brick wall ("montageskrue" in danish). These are by far the highest torque screws I have ever worked with. The early versions used Phillips rather than Torx, and nobody even bothers trying to get those loose before breaking out the saw.
