The countersink has an outer wall which connects with an inclined lower wall portion of a chuck wall at a junction below the center panel, and the chuck wall has a curved or inclined upper wall portion which connects with an inner wall of the crown. The chuck wall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall. The inclined upper wall portion of the chuck wall extends at an angle greater than the angle of the inclined lower wall portion of the chuck wall.
