A one piece metal fastener with a dish profiled head for mechanically securing drywall and insulated plasterboard panels to walls. Prevents dot and dab plasterboard from falling on persons escaping a blazing building, or on persons entering a blazing building for rescue purposes. The fire-proof metal fastener has a self-tapping helical shank with work hardened blades able to cut into a wide range of masonry.
Annular ring shank nails offer superior holding power over smooth shank nails as the wood fills in the crevasse of the rings and also provide friction to help prevent the nail from backing out over time. A ring shank nail is often used in softer types of wood where splitting is not an issue.
