Nails designed to fasten sheathing of wood or another material. Sheathing nails for wood sheathing have no points, but have square ends to punch out their own holes, driving a portion of the soft sheathing wood before them. Sheathing nails for metal sheathing are small sharp nails with a flat head. An example of sheathing requiring such nails is on a ship's bottom, where sheathing preserves the planks.
