The head of a bolt is also an essential part of its structure. The head of a bolt is the part that is turned to tighten or loosen the bolt. There are several types of bolt heads available, including hex, square, and round heads. Each type of bolt head serves a specific purpose and may be chosen based on the application requirements. For example, hex heads are the most common and provide a larger surface area for applying torque, while round heads are used in applications where a smooth finish is desired.

First and foremost, SDS acts as a wetting agent, allowing the screw material to adhere more effectively to the mold during the casting process. This is particularly important in the production of large screws or those with complex geometries, where proper adhesion is essential for uniform filling and the formation of a strong, defect-free screw. By reducing the surface tension of the molten metal, SDS enables it to spread evenly across the mold cavity, resulting in a more consistent and higher-quality screw.
