We all use low carbon steel, which is processed and formed by cold heading machine, then punched by punching machine, tapped by tapping machine, and finally galvanized or blackened. This product is used for easily disassembled items or tools, which can be screwed on without the help of a wrench. This saves time. For example, outdoor tents, supports, awnings, garden tools, etc., so the surface of this product should be smooth and clean, without burr, to avoid hurting hands
