One of the primary reasons for the popularity of stainless steel structural bolts is their durability. These bolts are made from high-quality steel that has been treated to resist corrosion and rust. This means that they can withstand harsh environmental conditions, including exposure to saltwater, chemicals, and extreme temperatures. As a result, stainless steel structural bolts have a longer lifespan than other types of bolts, reducing the need for frequent replacements and maintenance.

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.
