Heads blend in with common decking colors

GRK’s Kameleon™ screws are an excellent choice for composite and PVC decking applications. The underhead has saw-blade like cutting teeth that cut a perfectly clean hole into the decking. The Kameleon™ also features five to seven rings that have three indented fibre traps on each ring designed to trap fibres and eliminate the mushroom effect.

The Kameleon screws are self tapping featuring fibre trapping rings, a countersinking head with cutting teeth, CEE Thread™, W-Cut™ threads for reduced torque and our Climatek™ AC257 code approved coating. They are ESR code approved under ICC Report ESR-3201.

The CEE Thread feature enlarges the screw hole allowing the composite decking to settle easily, increases the screw’s drawing strength, and reduces the friction on the screw shank, which can result in lowering the overall driving torque. The Kameleon™ is also available in many different colors including: Grey, Brown, and Tan.


  • Recessed Star Drive: Zero Stripping, with 6 points of contact.
  • CEE Thread: Enlarges hole to reduce splitting, install torque.
  • W-Cut™: Low torque, smoother drive, reduce splitting.
  • Zip-Tip™: No pre-drilling, faster penetration, reduce splitting.
  • Fibre Trapping Rings: are designed to prevent mushrooming and dimpling.
  • Cutting Pockets: provide a clean hole, reduces splitting, and bore with precision.
  • ICC ESR-3201 Approved for structural application.
  • Case Hardened Steel: for high tensile, torque and shear strength.

  • For interior/exterior use in; both composite and PVC decking.
