Fibre Cement Board Screws

Fibre cement board screws are designed for securing cement boards, roofing sheets, and cladding panels to structural frames. Built for strength and weather resistance, they provide a secure fixing while maintaining a watertight seal in external applications.

Fibre Cement Screws at a Glance

What are fibre cement board screws?

Fibre cement board screws are specialist fixings used to secure fibre cement sheets, cladding panels, and roofing materials to structural frames. Unlike standard screws, they are designed to handle dense materials while preventing cracking and ensuring a strong hold.

Most fibre cement screws feature a self-drilling tip for metal applications, along with a sealing washer to prevent water ingress in exposed environments.

Which screws do I need for fibre cement boards?

The correct screw depends on the material you're fixing into. Use the guide below to choose the right option.

Application	Recommended Screw	Why
Fibre cement to light section steel	Self-drilling screws with EPDM washer	Drills through steel and seals against water ingress
Cladding and external boards	Corrosion-resistant coated screws	Prevents rust and extends lifespan
Roofing sheets and corrugated panels	Roofing screws with rubber washer	Creates a watertight seal at fixing points

Why use screws with EPDM washers?

Many fibre cement and roofing screws are supplied with EPDM rubber washers. These washers compress during installation to create a weatherproof seal.

• Prevents water penetration at fixing points
• Reduces risk of leaks in roofing and cladding
• Improves long-term durability
• Maintains flexibility in changing temperatures

Where are fibre cement screws used?

• Roofing sheets and corrugated panels
• Fibre cement cladding systems
• External wall boards
• Outbuildings, sheds, and agricultural structures
• Industrial and commercial installations

Types of fibre cement screws available

• Fibre Cement Board Screws – For Light Section Steel – self-drilling screws for fixing into steel
• Fibre Cement Board Screws – For Timber – specialist screws for timber fixing

Each type is designed to deliver reliable fixing performance depending on the material and environment.

Fibre Cement Screws FAQs

What screws should I use for fibre cement board?
Use specialist fibre cement screws designed for the substrate. Self-drilling screws are typically used for steel, while other types are designed for different fixing materials.

Do I need screws with a rubber washer?
Yes, for external or roofing applications. The washer creates a watertight seal and prevents leaks.

Can I use normal screws for cement board?
No, standard screws are not designed for fibre cement and may fail or cause cracking. Always use purpose-made cement board screws.

What are self-drilling screws for steel?
These screws have a drill point that allows them to cut through steel without pre-drilling, saving time on installation.

Are fibre cement screws suitable for roofing?
Yes, many are specifically designed for roofing sheets and include sealing washers for weather protection.
