4PRO Ring Shank Framing Nails 3.1 × 90 mm, 21°, Hot-Dip Galvanized

4PRO ring shank framing nails 3.1 × 90 mm are professional 21° collated nails designed for timber frame construction, load-bearing timber assemblies and other demanding woodworking applications. Manufactured from steel with a hot-dip galvanized coating, these nails provide improved corrosion resistance for suitable exterior timber structures.

The nails have a 3.1 mm diameter and 90 mm length, making them suitable for fastening substantial timber sections and structural wooden components. Their ring shank design increases resistance to nail withdrawal by providing additional mechanical grip within the wood.

The 21° strip collation allows fast, consecutive fastening with compatible pneumatic framing nailers, making these nails practical for professional construction and repetitive timber fastening tasks.

Ring Shank for Improved Withdrawal Resistance

The distinctive annular ring shank features a series of ridges along the nail shaft. These ridges increase the mechanical grip between the nail and surrounding wood fibres, helping resist nail withdrawal.

Compared with smooth shank nails of otherwise comparable specification, ring shank nails generally provide greater resistance to being pulled out of timber.

This design makes the nails particularly useful for suitable timber assemblies where reliable fastening and resistance to loosening are important.

Hot-Dip Galvanized Corrosion Protection

The hot-dip galvanized steel nails have a protective zinc coating that improves corrosion resistance compared with uncoated carbon steel fasteners.

The coating makes them suitable for appropriate outdoor timber construction and environments subject to changing weather conditions. The suitability of the coating should be assessed according to the exposure conditions and project requirements.

21° Collation for Pneumatic Framing Nailers

The nails are supplied in 21° collated strips, designed for use with pneumatic framing nailers supporting the specified nail diameter, length and collation format.

Strip collation allows repeated fastening without loading each nail individually, supporting efficient assembly of timber frames and other wooden structures.
