A self-drilling screw with a hex head, typically coated with white zinc plating, is a type of fastener designed for ease of installation without the need for pre-drilling. These screws feature a hexagonal (hex) head, allowing them to be driven using a wrench or socket wrench for greater torque and control during installation.
The self-drilling feature of these screws means that they have a drill bit-like tip that can penetrate and drill through materials such as metal or wood while simultaneously fastening them together. This eliminates the need for separate drilling before inserting the screw, saving time and effort during assembly.
The white zinc plating coating provides corrosion resistance, protecting the screw from rust and oxidation, particularly in outdoor or high-moisture environments. This makes them suitable for various applications, including construction, carpentry, metalworking, and general DIY projects where a secure and durable fastening solution is required.
