Our Truss Head Self-Drilling Screws are the ultimate all-in-one fastening solution, engineered to dramatically increase efficiency by drilling, tapping, and fastening in a single, seamless operation. These screws feature a specially designed drill point that eliminates the need for pre-drilling, allowing you to fasten directly into metal and other materials. The screw is topped with a low-profile truss head, which provides a wide bearing surface to distribute the clamping load and prevent pull-through on thin materials like sheet metal. Ideal for building and construction applications, these screws save significant time and labor while ensuring a secure and reliable connection.
The superior functionality of our self-drilling screws lies in their innovative design. The hardened drill point acts as a miniature drill bit, cleanly cutting through the material to create a perfectly sized hole. As the screw is driven further, the subsequent threads tap into the newly drilled hole, forming a tight, precise mating thread for maximum holding power.
The truss head, with its wide, slightly rounded top and low profile, is specifically designed for applications involving thin gauge materials. It offers excellent clamping force without deforming the surface and provides a finished look with minimal obstruction. Manufactured from high-quality steel (such as C1022A) or corrosion-resistant stainless steel (Grades A2-70, A4-70), and available with protective zinc plating, these screws are built for durability and long-lasting performance.
