Hammer 2.5-Inch Galvanized Roofing Nails with Washers, 1kg Pack

2.5-Inch Galvanized Roofing Nails

The Hammer 2.5-Inch Galvanized Roofing Nails with Washers, 1kg Pack provides a heavy-duty fastening solution for corrugated metal and fiber cement sheets. These fasteners feature a hot-dipped zinc coating for corrosion resistance in exterior environments. They ensure structural integrity on timber-framed structures.

Built for the Job

Roofing contractors require fasteners that withstand high wind loads and heavy rainfall. These items utilize a wide umbrella head to distribute pressure across the surface of the roofing sheet. This design prevents the fastener from pulling through the material during thermal expansion or high winds. The inclusion of a pre-fitted rubber washer ensures a watertight seal at every penetration point. The galvanization process involves coating the steel in zinc to prevent oxidation. This sacrificial layer is critical for long-term structural integrity on exposed roofs. When driving these into timber purlins, the smooth shank provides high withdrawal resistance and easy penetration without splitting the wood.

• Securing corrugated iron sheets to timber purlins in residential and commercial builds.

• Installing box profile roofing sheets where a large head diameter is required for stability.

• Fixing fiber cement roofing components in agricultural or industrial environments.

Product Highlights

Umbrella Head Design

The large 20mm head diameter covers the puncture hole effectively to prevent water ingress and sheet lift.

Corrosion Protection

• Hot-dipped galvanized finish for rust resistance in humid climates.
• Durable steel core maintains tensile strength under environmental stress.

Technical Specifications

What’s Included

• 1kg Bulk Pack of Galvanized Nails with Washers

On-Site & Workshop Notes

• Always drive the nail through the crown of the corrugated sheet to ensure water flows away from the puncture.

• Do not over-drive the fastener, as this can crush the rubber washer and compromise the watertight seal.

• Store in a dry location to maintain the integrity of the packaging and prevent clumping of the washers.

• Use a standard claw hammer for installation; ensure the nail is driven perpendicular to the timber purlin.
