The invention discloses a thread rolling plate and a thread rolling machine. The thread rolling plate is of a plate-shaped structure, and at least one tooth body is arranged on one face of the thread rolling plate; and all tooth bodies extend along the surface of the thread rolling plate, and at least one tooth body is provided with a step-shaped structure. The thread rolling machine comprises the two thread rolling plates, the faces, provided with the thread bodies, of the two thread rolling plates are oppositely arranged in parallel, one thread rolling plate can move in parallel relative to the other thread rolling plate, and the extending direction of the thread bodies of one thread rolling plate intersects with the extending direction of the thread bodies of the other thread rolling plate. By the adoption of the thread rolling plate or the thread rolling machine, the step-shaped external threads can be directly extruded on the to-be-machined part or structure at a time, and the threaded part with the step
