- Tri-Lobe Thread Design - provides a strong, secure hold in composite and PVC decking materials, minimizing the risk of fastener back-out over time.
- Cap Head with 0.230 in. Diameter - wide head distributes load evenly across the decking surface for a stable, lasting connection.
- T20 6-Lobe Drive Type - delivers superior torque transfer and reduces cam-out during driving, giving installers better control and a cleaner result.
- Gray Color-Matching Painted Head - blends with popular composite decking manufacturers' colors for a more concealed, professional appearance that eliminates the look of exposed fasteners.
- Available in a wide range of colors - a single screw solution compatible with numerous decking brands, removing the need to mix and match fasteners for different decking products.

Why This Product
- The Type-17 self-drilling point combined with inverted upper threads means composite material is cleared efficiently as the screw drives in - resulting in a flush, surface-clean installation without the extra step of pre-drilling.
- The Quik Guard coating provides targeted corrosion resistance for outdoor deck board applications, giving builders confidence that fasteners will hold up in typical exterior conditions over the long term.
- Color-matching gray painted heads blend with the decking surface so finished decks look professional and polished - no visible silver hardware detracting from the aesthetic of the composite boards.
- Engineered exclusively for composite and PVC decking, this screw eliminates the guesswork of selecting a general-purpose fastener and ensures performance that matches the demands of modern composite deck board materials.
