| Description: |  | The adjusting screw rotates on the cylindrical shank, and engages threads cut on the interior of the movable jaw base.  The wrench handle can swing, and has a short lip that bears on the base of the adjusting screw.  Pulling on the handle exerts force on the base of the adjusting screw, and increases the gripping force of the wrench. |  |
