FAQs

Can I use a Phillips head screwdriver for these screws?

No. These screws are designed for a No.2 Square Bit. Using a Phillips head will strip the screw head immediately.

Are these screws suitable for pressure-treated timber?

These are specifically designed for composite decking and cladding. While they may drive into timber, they are optimized for the density and mounting requirements of composite materials.

Do I need to pre-drill pilot holes?

For most composite materials, pre-drilling is recommended to prevent the boards from cracking or 'mushrooming' around the screw head.

What happens if I lose the Square Bit tool?

You must obtain a replacement No.2 Square Bit before continuing the installation to avoid damaging the fasteners or the decking boards.

Are these screws weather-resistant?

Yes, they are designed for outdoor use and are manufactured to resist corrosion common in exterior decking environments.

Troubleshooting

Screw head stripping

Ensure you are using a dedicated No.2 Square Bit and that the bit is fully seated before applying pressure.

Screw will not sit flush

Check that there is no debris between the board and the joist or that the screw is not hitting a metal bracket underneath.

Pros and Cons

Pros

  • Seamless visual finish due to colour-matching
  • High-quality construction for outdoor durability
  • Reduced risk of fastener stripping with the correct drive tool
  • Ensures a professional, uniform look across the entire deck surface

Cons

  • Requires a specific No.2 Square Bit
  • Not intended for use with natural timber boards
  • Cannot be installed with standard Phillips or flat-head drivers

Setup, Compatibility & Care

For a successful installation, ensure your drill is set to a medium-low torque setting to prevent over-tightening or damaging the composite material.

Compatibility Requirements:

  • Tooling: A No.2 Square Bit is required. Attempting to use a different bit type will result in damage to the screw head.
  • Material: Designed for use with composite decking and cladding. Not recommended for use with hardwood or softwood decking unless specified.

Care Instructions:

  • Store in a dry environment prior to installation to maintain the integrity of the coating.
  • Keep the thread clean of debris during installation to ensure a smooth drive into the joist.
