Class 3 Counter Sunk
Delivery or Click & Collect
Edcon Steel’s self-drilling countersunk screws are equipped with a moderate zinc (Class 3) coating, making them well-suited for general outdoor and mild industrial applications with low to moderate moisture exposure. They combine drilling and fastening in a single step—drilling into metal (typically a few millimetres) without pre-drilling—and feature a flush, countersunk head for a clean, discrete finish in steel cladding, frame construction, and light fabrication applications.
Search Class 3 Counter Sunk only.
