PURPOSE: A trim steel coupled to blanking die is provided to improve quality of blank produced by the trim steel by improving straightness of the trim steel coupled to the blanking die. CONSTITUTION: The trim steel coupled to blanking die is characterized in that a plurality of first bolt members (10) are clamped to one side of the trim steel (100) so that the trim steel is connected to the blanking die, and a plurality of second bolt members (20) for connecting the trim steel to the blanking die are clamped perpendicularly to one direction of the trim steel so that the trim steel is connected to the blanking die, first bolt holes (13) are formed at one side of the trim steel (100), second bolt holes (21) are formed perpendicularly to the first bolt holes (13), first connecting holes (15) are formed on the blanking die (11) so that the first bolt members (10) connected to the first bolt holes (13) are connected to the blanking die (11), second connecting holes (23) are formed on the blanking die (11) so that the second bolt members (20) connected to the second bolt holes (21) are connected to the blanking die (11), and the second bolt members (20) are connected to the trim steel (100) in such a way that the second bolt members (20) are positioned between the first bolt members (10) in the trim steel (100).
