Self Drilling Screws for Thick Steel
Construction Fastening Systems supplies professional-grade self drilling screws for thick steel designed to drill, tap, and fasten in one operation. These heavy-duty steel fasteners feature long drill points that penetrate thicker structural steel without requiring a separate pilot hole in many applications, helping contractors save time while creating strong, dependable connections.
Our hex washer head self drilling screws are ideal for fastening steel to steel in commercial construction, metal fabrication, electrical installations, HVAC work, equipment mounting, and structural framing.
Designed for Heavy Gauge Steel
Unlike standard self drilling screws intended for light sheet metal, these heavy-duty screws utilize extended drill points specifically engineered for thicker steel sections. Longer drill flutes remove metal chips more efficiently while reducing heat buildup during installation, allowing faster drilling and longer tool life.

How to Choose the Right Thick Steel Self Drilling Screw
Selecting the proper screw starts with determining the total thickness of the materials being fastened together. As steel becomes thicker, a longer drill point is required to efficiently remove metal chips and prevent excessive heat buildup. Using the proper drill point improves drilling speed, extends screw life, and helps produce secure threads.
