Series 500 Hex with Seal

These high-performance fasteners—also known as Series 500 or 5-series Tek screws—feature a hardened No. 5 drill point and fine thread profile that allows them to drill through up to 12 mm of mild steel without the need for pre-drilling. They include an EPDM sealing washer, providing a robust watertight seal, enhancing wind uplift protection, and making them ideal for structural framing, cladding, HVAC, and fabrication in both internal and harsh external conditions. Available in durable Class 4 galvanised or stainless finishes, these screws balance corrosion resistance with strength and efficiency
