Stainless Steel Composite Deck Screw
SS305, 304 and 316
StainGrip® Stainless Steel Trim Head Torx Drive Composite Deck Screws are professional-grade trim head deck screws engineered for superior holding power and seamless finishing in PVC and composite decking boards. Manufactured from premium SS304, SS305, and marine-grade SS316 stainless steel, these Composite deck screws provide ultimate corrosion resistance while preventing surface splitting and board damage.
Key Features & Technical Benefits
· Special Undercut Head & Reverse Thread (Anti-Mushrooming): Designed with a specialized undercut head and reverse upper threads that press composite fibers back into the hole. This uniquely eliminates mushrooming around screw hole areas, leaving a clean, perfectly flush surface without unsightly bumps or burrs.
· Type 17 Auger Point (Self-Drilling Point): Features a razor-sharp type 17 point that slices through hard composite deck with ease. Enjoy quick drive times with no pre-drilling required in composite decking under standard operating conditions.
· Deep Star Drive / Torx Drive: Precision-molded T20 / T25 Star Drive deep recess ensures superior anti-stripping torque transfer, eliminating bit cam-out, drive slippage, and stripped screw heads during heavy-duty installation.
· Color-Matched Painted Head: Expert composite board color matching with durable painted head deck screwsdesigned to blend invisibly with top composite board colors (including Teak, Charcoal, Cedar, Sand, and White).
