Abstract
A fastener removal device for accessing and securing a fastener head while in a dirty environment features a cylindrical nut driver. A driver first end features a nut driver head having a hexagonal recess centrally located on a nut driver first end surface. A bottom surface of the hexagonal recess is located on a hexagonal recess plane. The hexagonal recess plane is located parallel to and offset from the nut driver first end surface. The hexagonal recess is adapted to engage with a head of a fastener. A plurality of helical flutes is located around a driver first end outer periphery. A flute first end intersects the nut driver first end surface. A flute second end intersects the hexagonal recess plane. The driver second end features a hexagonal shank adapted to engage a drill chuck of a drill.
