Reliable Fixing for Sheet Metal & Plastics with an Integrated Flange Head
These 25mm x 4.2mm flange head self-tapping screws from TIMCO are engineered for secure fastening into thin metals and rigid plastics, eliminating the need for pre-drilling in most applications. Their built-in flange head provides a broader bearing surface — distributing load evenly and preventing material damage — making them ideal for metal panels, signage, trays, ducts, and enclosures.
The 25mm length gives additional grip for deeper substrates or slightly thicker gauge steel. Combined with a sharp point and fully threaded shank, these screws are optimised for quick installations in busy trade environments. The Pozi drive allows for fast, slip-free fixing with minimal cam-out.
Constructed from carbon steel with a BZP (Bright Zinc Plated) finish, these screws offer internal corrosion resistance and a smooth finish suited to visible installs where a clean metallic look is preferred.
Key applications include: HVAC ducts, signage trays, vehicle linings, perimeter trims, and general light fabrication.
