Jcp Fixings Fibre Cement Screws - Silver

These screws are specifically designed for heavy-section applications, making them ideal for securely attaching cladding and other materials to fibre cement boards.

BZP stands for Bright Zinc Plated. This is a metallic coating applied to the screws to provide excellent resistance to corrosion and rust, making them suitable for exterior use.

They are best suited for fibre cement cladding and similar dense sheet materials. While they can be used with timber or metal sub-structures, their design is optimized for fibre cement.

The screws measure 6.3mm in diameter and 110mm in length, an optimal size for heavy-duty applications requiring deep penetration.

You will need a power drill or impact driver with the appropriate driver bit for the screw head. It's important to use correct torque settings suitable for fibre cement.

Yes, they can be used for interior projects, but their robust design and corrosion resistance are particularly beneficial for exterior applications.

Use the correct torque setting on your power tool, ensure the driver bit is properly seated, and drive the screw straight. Pre-drilling pilot holes can also help prevent cracking, especially in denser or more brittle sections.

Ensure you are using the correct size driver bit and that it is fully seated in the screw head. Reduce the torque setting on your power tool and ensure the screw is not encountering excessive resistance. Pre-drilling may be necessary.

The torque setting may be too high, or the material may be too brittle. Try reducing the torque and ensure the screw is driven straight. Consider pre-drilling a pilot hole slightly smaller than the screw's core diameter.

Verify that the screw is long enough to achieve adequate penetration into the structural substrate behind the fibre cement. Ensure the substrate is sound and suitable for fixing. Check for any damage to the screw threads.

While the BZP finish is durable, extreme environmental conditions can eventually impact it. Ensure screws are stored dry before use. For new installations showing early corrosion, consider if a more robust coating is required for the specific environment.
