Drilling Class 4 Hex - Corse

Delivery or Click & Collect

Edcon Steel’s Coarse‑Thread Class 4 self‑drilling fasteners (hex head) boast a thick, heavy-duty zinc coating that offers superior corrosion resistance—perfect for coastal, industrial, and heavily exposed environments. Featuring a hardened TEK-style drill point capable of drilling through up to 4.5 mm mild steel, these screws also often include flanged or sealing washers—which enhance load bearing and wind uplift protection—making them particularly effective for metal‑to‑metal fastening, structural framing, and sheet cladding applications.
