Extended Product Information

FAQs

Are these screws suitable for hardwood decking?

They can be used in some hardwoods, but pre-drilling is essential to avoid snapping or splitting.

Can these screws be painted?

The green coating is designed for durability; painting is possible but may require a primer for the paint to adhere properly.

Are these stainless steel?

No, they are carbon steel with a protective green coating for corrosion resistance.

What is the screw length in millimeters?

These screws are 75mm long.

Do I need to buy a special driver bit?

You need a standard Pozi-drive bit that matches the 10g screw specification.

Troubleshooting

Screw head stripping

Ensure you are using the correct size Pozi-drive bit and apply firm, steady forward pressure while driving.

Timber splitting

Reduce the torque on your driver and pre-drill a pilot hole before inserting the screw.

Screw not sitting flush

Countersink the timber slightly more or ensure the drill depth is sufficient for the screw length.

Pros and Cons

Pros

  • High corrosion resistance for exterior longevity
  • Countersunk design ensures a flush, professional finish
  • Generous 375-screw count for large projects
  • Ideal length for standard decking boards

Cons

  • Requires specific Pozi-drive bit size
  • Green coating may be visible if not fully countersunk
  • Not suitable for use in highly acidic woods like green oak without pilot holes

Setup, Compatibility & Care

To ensure the longevity of your decking, always select a drill bit slightly smaller than the shank diameter of the screw for pilot holes. For maximum performance, check that your power tool is set to an appropriate torque setting to avoid stripping the Pozi recess. While the green coating offers robust rust protection, it is advisable to keep the box in a dry, covered area to prevent moisture buildup within the packaging. If you notice any screws showing signs of damage or deformed threads, discard them immediately to maintain the structural integrity of your build.
