countersunk self drilling screws for steel

Stitch Tek screws, also known as stitch or track screws, are specifically designed for heavy-duty applications where high tensile strength and resistance to shear forces are paramount. The term 'Stitch Tek' refers to their unique threading pattern and design that allows them to securely anchor into materials, providing an unparalleled level of stability. Their innovative design, characterized by closely spaced threads, enables a faster and more efficient installation process, reducing project timelines and overall costs.

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.
