Description

The Simpson Strong-Tie Deck-Drive™ DCU Composite Screw is the go-to fastener for composite and PVC decking, trim, and cladding. Featuring a cap head that prevents mushrooming, these screws deliver a smooth, professional finish while blending seamlessly with your deck surface. Available in a wide range of colors matched to leading composite decking brands, the DCU eliminates the need to mix and match fasteners.

Built for long-term performance, the screw’s tri-lobe thread design and unique cut point drive cleanly into composite and PVC material without splitting or excess board damage. Inverted upper threads clear material away for flush seating, while 316 stainless steel provides maximum corrosion-resistance in marine environments.

Key Features

  • Cap head design - prevents mushrooming for a smoother, cleaner finish
  • Tri-lobe thread design - reduces damage to composite boards during installation
  • Inverted upper threads - clear excess material for a flush fit
  • Unique cut point - allows fast starts in composite, PVC, and HDPE materials
  • Color-matched options - blends with most major decking manufacturers’ products
