External Washer     
  A hardened circular washer with twisted prongs or "teeth" which extend
out from the outer edge of the washer.

  This is preferred when finished appearance is crucial and the teeth must be hidden under the head of the screw; also recommended for use with small heads such as fillisters.

Internal Washer
  A hardened circular washer with twisted prongs or "teeth" which extend
inward from the inside edge of the washer.

  This is the most preferable of all tooth-lock washers.  It offers the greatest locking efficiency since the teeth are on the largest radius and provide greater torsional resistance.
