Extended Product Information

FAQs

Does this pack include the required drill bit?

No, the No.2 Square Bit is sold separately.

Can these be used for hardwood decking?

These are designed specifically for composite decking and cladding; performance on natural timber is not guaranteed.

How many screws are in a pack?

Each pack contains 50 screws.

What length are these screws?

These screws are 40mm long.

Are these screws rust-proof?

They are designed for exterior use, but we recommend keeping them in a dry place before installation to prevent surface oxidation.

Troubleshooting

Screw head keeps stripping

Ensure you are using the correct No.2 Square Bit and check that your drill speed is set low.

Screw is difficult to drive into the board

Pre-drill a small pilot hole to reduce resistance, especially when working with denser composite materials.

Surface of the board is raised around the screw

Ensure the screw is driven straight and reduce the torque setting on your drill.

Pros and Cons

Pros

  • Seamless aesthetic finish that blends into the deck surface
  • Prevents unsightly hardware visibility
  • Specialized design minimizes damage to composite materials
  • Durable construction suitable for exterior use

Cons

  • Requires a specific No.2 Square Bit not included in the pack
  • Limited to specific grey-toned decking systems
  • Cannot be used on natural timber without potential finish issues

Setup, Compatibility & Care

To install these screws, you must use a No.2 Square Bit; using a standard Phillips or flat-head screwdriver will likely strip the head of the screw and damage the composite surface. Ensure your impact driver or drill is set to a low-torque setting to avoid over-tightening. For ongoing care, periodically check for any loose fixings after significant weather changes, as composite materials can expand and contract slightly with extreme temperature fluctuations. Always store unused screws in a dry environment to prevent premature oxidation.
