Series 500 Wafer

These premium Series 500 self-drilling screws—also known as 5‑Series Tek screws—feature a hardened No. 5 drill point and fine thread profile, capable of penetrating up to 12 mm of mild steel without pre-drilling—ideal for efficient metal-to-metal assembly in structural framing, HVAC, fabrication, and purlin work. The wafer-style low-profile head delivers a clean, unobtrusive finish while offering high pull-out strength and secure fastening—available in durable Class 4 galvanised and stainless steel finishes for both internal and high-exposure environments.
