Flush, Clean Fixings for Sheet Metal, Plastic & Lightweight Timber
These 25mm x 4.2mm countersunk self-tapping screws are ideal for applications where a smooth, flush surface is required. The countersunk Pozi head sits neatly below the surface, making these fixings perfect for sign trays, panelwork, and joinery-grade finishing. The sharp self-tapping thread easily cuts into metal, plastic, and thin wood without needing a pilot hole — ideal for fast-paced trade jobs.
With extra length compared to the 19mm variant, these screws offer improved grip in deeper substrates or layered material setups. Their BZP (Bright Zinc Plated) finish provides a clean metallic appearance and resistance to corrosion in internal or sheltered environments.
This screw is part of TIMCO’s premium BZP self-tapping range and comes boxed in quantities of 200 for convenience and value.
Ideal uses include: signmaking, rigid plastic installations, perimeter trims, light enclosures, brackets and frames.
