Tri-Fixx Poly-Fixx Polycarb Metal Screws 12-14 x 60mm – Dome Washer (Bag of 250)

The Tri-Fixx Poly-Fixx Polycarb Metal Screws are purpose-designed for fastening polycarbonate sheeting to metal structures with maximum strength, weather protection, and long-term performance. Built for Australian conditions, these screws ensure a secure, watertight installation every time.

Key Features

  • Engineered for Metal Fixing: 12-14 gauge threads provide strong engagement and high pull-out resistance in metal substrates.
  • Flexible UV-Stabilised EPDM Washer: Creates a long-lasting, watertight seal between the screw head and the polycarbonate sheet, preventing leaks and reducing sheet damage.
  • One-Step Installation: No pre-drilling required—faster, cleaner, and easier installation.
  • Integrated Cutting Tool: Forms an expansion hole in the polycarbonate sheet as you drive the screw, preventing buckling or stress caused by temperature changes.
  • C4 Rated Anti-Corrosion Coating: Delivers superior resistance to rust and environmental exposure, ideal for outdoor and coastal applications.
  • Reliable Dome Washer Design: Distributes pressure evenly to avoid overtightening and protect polycarbonate roofing.
  • Bag of 50: Perfect for carports, pergolas, verandahs, and other polycarbonate roofing projects.

Ideal For

  • Polycarbonate roofing and cladding
  • Metal-framed pergolas, verandahs & patios
  • Carports and outdoor structures
  • Greenhouses with steel supports
