slotted hex washer head screw

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.

The design of tek screws is one of their most appealing aspects. Generally, they have a hex, torx, or slotted head, which facilitates easy application using power tools. The self-drilling tip is sharp, which allows it to penetrate materials without requiring an additional drill bit. Furthermore, the threading on a tek screw is optimized for a variety of materials, including metal, wood, and plastics, enabling it to secure different substrates firmly.
