Eine hochfeste Schraube (1) weist einen Kopf (2) mit einer Werkzeugangriff-Außenkontur (7) und einer Werkzeugangriff-Innenkontur (8) auf. Bei der Werkzeugangriff-Außenkontur (7) handelt es sich z. B. um einen Außensechskant und bei der Werkzeugangriff-Innenkontur (8) um einen Innensechskant. In der Werkzeugangriff-Innenkontur (8) sind zwischen den Ecken (12) taschenförmige Vertiefungen (13) angeordnet. A high-strength screw (1) includes a head (2) having a tool engagement external contour (7) and a tool engagement internal contour (8). For example, the tool engagement external contour (7) is an external hexagonal and the tool engagement internal contour (8) is an internal hexagonal. A plurality of additional pocket-shaped impressions (13) are arranged in the tool engagement internal contour (8) between corners (12).
