FAQs

What size drill bit should I use?

Use a drill bit appropriate for a 5mm screw, typically around 4mm.

Can I use these screws on metal roofing?

No, these screws are designed specifically for corrugated sheeting and timber subframes. Do not use them on metal roofing.

What type of screwdriver do I need?

You will need a Pozidriv screwdriver or bit, the head has additional contact points compared to a Phillips head.

How do I prevent the plastic cap from cracking?

Avoid over-tightening the screws. Tighten until the cap seals the roof, but not so much that it deforms or cracks.

Are these screws suitable for outdoor use?

Yes, the zinc plating and plastic cap are designed to withstand outdoor conditions.

How do I know if the screws are installed correctly?

The plastic cap should sit flush against the corrugated sheet, creating a seal. The screw should be firmly embedded in the timber frame.

What is the purpose of the plastic cover cap?

The plastic cover cap improves weather resistance by creating a seal and preventing water ingress around the screw head.

Troubleshooting

Screw is not holding securely.

Ensure the pilot hole is the correct size. If the timber is old, consider using a slightly longer screw or wood filler to reinforce the screw's grip.

Plastic cap is damaged.

Replace the screw. Be careful not to over-tighten screws during installation.

Screw head is stripped.

Use a new screw. Ensure the correct Pozidriv bit is being used, and apply firm, even pressure when driving the screw.

Corrosion visible on the screw.

Check if the zinc coating is damaged, if so, replace the screw. Make sure there isn't any damage or wear to the protective plastic cap.

Setup, Compatibility & Care

  1. Preparation: Ensure the timber subframe is properly aligned and in good condition. Measure and mark the locations for the screws.
  2. Pre-Drilling: Pre-drill pilot holes in the corrugated sheeting and timber frame to prevent splitting and ensure a secure fit. The drill bit size should be appropriate for the screw size (5mm).
  3. Screw Installation: Insert the screw through the corrugated sheet and into the timber frame. Use a Pozidriv screwdriver or bit.
  4. Tightening: Tighten the screws until the plastic cap sits firmly against the corrugated sheet, creating a weather-resistant seal. Avoid over-tightening.
  5. Compatibility: These screws are specifically designed for use with corrugated sheeting and timber subframes. Ensure the screw length is appropriate for the thickness of the materials.
  6. Care: Regularly inspect the roof for any loose or damaged screws. Replace any damaged screws promptly to maintain the roof's integrity. Clean the roof as needed to remove debris and prevent build-up.
