    Abstract: A fastener for driving into a substrate has a head having an upper surface and a lower surface, a penetrating tip and a shank extending from the lower surface of the head to the penetrating tip. At least one deformable feature is formed on the head. The deformable feature is configured to absorb energy and to deform. When a driving element is driven onto the head to drive the fastener into the substrate, the deformable feature absorbs energy and is deformed as the head contacts the substrate.
