Secure Fixing for Deeper Substrates & Metal-to-Metal Applications

These 25mm x 4.2mm wafer head self drilling screws are ideal for fastening into thicker sheet metal, light gauge steel, and layered material setups without the need for a pilot hole. The extra length provides deeper bite and increased holding strength - perfect for robust internal framing, HVAC trays, and heavy signage systems.

The wide, low-profile wafer head distributes pressure evenly and ensures a flush finish. With a Phillips No. 2 drive and self-drilling (tek) point, these screws are designed for speed and efficiency across high-volume install jobs.

The BZP (Bright Zinc Plated) finish provides a clean metallic look and protection against corrosion in internal or sheltered environments.

Typical uses include: electrical tray systems, aluminium trims, ducting, signage frames, and metal cladding supports.
