A fastening system comprising:
- a tool element for facilitating driving of a screw comprising
- a blade, comprising a blade front surface, a blade rear surface, a blade left surface and a blade right surface;
- a flared drive, a top end of the flared drive being fixed to a bottom end of the blade, and the flared drive comprising:
- a flared drive bottom end;
- a flared drive front surface, the flared drive front surface being coplanar with the blade front surface and extending from the blade front surface to the flared drive bottom end;
- a flared drive rear surface, the flared drive rear surface being coplanar with the blade rear surface, extending from the blade rear surface to the flared drive bottom end and being parallel with the flared drive front surface;
- a flared drive left surface outwardly extending from the blade left surface to the flared drive bottom end to form a first angle;
- and
- a flared drive right surface outwardly extending from the blade right surface to the flared drive bottom end to form a second angle;
- and
- a substantially rectangular shank drive, a top end of the substantially rectangular shank drive being fixed to the flared drive bottom end, and the substantially rectangular shank drive comprising:
- a shank drive bottom surface;
- a shank drive left surface;
- a shank drive right surface being parallel with the shank drive left surface;
- a shank drive front surface, the shank drive front surface being coplanar with the flared drive front surface;
- a shank drive rear surface, the shank drive rear surface being coplanar with the flared drive rear surface and being parallel with the shank drive front surface;
- a screw having a body and a head, the head comprising:
- a slot aligned along an axis aligned with a diameter of the head and comprising:
- a slot front inner surface;
- and
- a slot rear inner surface;
- a substantially rectangular shank set formed below the slot, aligned along the axis and comprising;
- a shank set front inner surface coplanar with the slot front inner surface;
- and
- a shank set rear inner surface coplanar with the slot rear inner surface;
- and
