Installation Guidelines

• Install at a true 90° angle to the surface; angled entry can damage the thread profile
• Select a length that ensures sufficient penetration through the material into the support; adequate engagement is essential for security
• In high‑wind or heavy‑snow zones, spacing must follow the relevant project engineering calculations
• Use a suitable gasket between dissimilar metals to prevent galvanic corrosion
• Check the seal around the head after installation; apply sealing tape or washers where required
• Store in a dry environment in original packaging; avoid prolonged exposure to moisture or water

Frequently Asked Questions

Does it need a pilot hole?
No — the self‑drilling point enables direct installation on steel and timber of appropriate thickness. A pilot hole is recommended for extra‑thick or very hard materials.

Suitable for outdoor use?
Yes — the galvanised finish provides excellent resistance to weathering. For coastal or high‑salinity environments, consider options with additional protective coating.

Can it be used in timber?
Yes — ideal for securing metal sheets and profiles to wooden beams and supports.

How long will it last?
Properly installed and periodically inspected, these screws will provide reliable service for decades.

Can I buy them individually?
This product is supplied in factory‑sealed packs of 1,800 pieces, priced and packaged specifically for bulk usage.
