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.

Black phosphate drywall screws are specialized fasteners designed specifically for the installation of drywall and related materials. They are characterized by a unique black phosphate coating that not only enhances their aesthetic appeal but also provides increased corrosion resistance. This coating is produced through a chemical process that creates a layer of iron phosphate on the screw's surface. This is crucial in construction environments where exposure to moisture and varying temperatures can lead to rust and degradation of standard screws.

Chemical resin bolts typically consist of two primary components the bolt itself, which is often made from high-quality steel, and the surrounding resin cartridge. The resin is a carefully formulated mixture of synthetic polymers and other compounds that react when forced out of the cartridge by the bolt's threading action. Once activated, this resin expands and solidifies, forming a secure anchor around the bolt within the drilled hole.
