ABSTRACT:
An eagle wing tips tamper-proof fastener and driver tool with complementary driver head contact for operating the same. A conventional threaded shank is perpendicularly connected to a substantially flat head. The head comprises a plurality of recessed channels numbering three and the channels radially curve outwards from a common center point. In one embodiment, the substantially vertical right and left walls of each channel allow application of torque with the driver tool in both directions. In an alternate embodiment, the substantially vertical right wall and the surface of the substantially inclined left wall allow application of torque with the driver tool to the right only.
