Product Information
Full details
The Unifix Slab Nails are heavy-duty fasteners designed for construction professionals and DIY enthusiasts who need to secure insulation boards to timber framing. Their primary benefit is a large-head design that provides superior holding power for soft or rigid insulation materials, though their 180mm length makes them unsuitable for thin-profile materials or shallow framing applications.

FAQs
Are these nails suitable for external use?
Yes, the galvanised finish provides protection against corrosion, making them suitable for use in exterior timber frames, provided they are covered by siding or a weather-resistant barrier.
Can I use these nails with metal framing?
No, these nails are specifically designed for timber penetration. They will not provide secure attachment to metal studs.
How many nails are in a 4kg tub?
While the exact count varies slightly due to manufacturing tolerances, 4kg provides a substantial quantity suitable for large-scale insulation jobs.
Will these nails rust if used in damp conditions?
The galvanised coating is designed to resist rust, but it is best to ensure they are protected from direct exposure to water to maximize their lifespan.
Can these be used for roofing insulation?
They are ideal for timber-frame wall insulation. For roofing, ensure that the depth of the nail does not penetrate through the exterior roof decking.
Troubleshooting
Nail head creates a depression in the insulation
Reduce the force of the final strike as the nail approaches the surface to ensure it sits flush without over-driving.
Difficulty driving the nail into very hard timber
Apply a small amount of lubricant to the shank or use a pilot hole to assist the initial penetration.
Nail bending during installation
Ensure the hammer strike is centered and direct; repeated off-center strikes will cause the long shank to buckle.

Setup, Compatibility & Care
Setup and Compatibility
- Compatibility: Designed specifically for timber framing. They are not intended for use with metal studs, masonry, or concrete.
- Hammering: Best installed using a standard claw hammer or framing hammer. Ensure the nail is driven perpendicular to the surface for maximum holding force.
Care and Storage
- Storage: Keep the tub tightly sealed in a cool, dry place to maintain the integrity of the galvanised coating.
- Maintenance: Avoid exposure to standing water or harsh chemicals that could compromise the galvanised finish over time.
