Class 3 Counter Sunk with Wings

Delivery or Click & Collect

Edcon Steel’s Class 3 self-drilling screws feature a moderate zinc plating, providing dependable corrosion resistance tailored for general outdoor and light–industrial applications with minimal moisture exposure. These screws come with a countersunk head and integral wings that first slice through timber to create a clearance hole and then snap off as the drill point penetrates metal—combining pre-drilling, countersinking, and fastening in one smooth operation, saving time and ensuring clean, flush installation in steel cladding, framing, and fabrication tasks
