To provide a screw nail capable of suppressing inclination at the time of striking, while suppressing influence of deformation due to striking.SOLUTION: A screw nail 1A comprises a nail shaft part 2 extending along one direction, and a head part 3 whose diameter is expanded along another direction orthogonal to the extension direction of the nail shaft part 2. A projection part 32 projecting along an axial direction of the nail shaft part 2 is formed on an end surface 30 of the head part 3 opposite to a side where the nail shaft part 2 projects. A recess part 33 is formed between the projection part 32 and an engagement part 31 that can be engaged with a rotary tool, and is concave with respect to the projection part 32 along the axial direction of the nail shaft part 2. A virtual plane contacting a vertex of the projection part 32 is perpendicular to the axial direction of the nail shaft part 2.SELECTED DRAWING: Figure 1A
