   {Fox wedge} (Mach. & Carpentry), a wedge for expanding the
      split end of a bolt, cotter, dowel, tenon, or other piece,
      to fasten the end in a hole or mortise and prevent
      withdrawal. The wedge abuts on the bottom of the hole and
      the piece is driven down upon it. Fastening by fox wedges
      is called foxtail wedging.
