The Unifix Sherardised Annular Ring Shank Nails are designed for professional contractors and dedicated DIY enthusiasts who require superior holding power in wood construction projects. The primary benefit of these nails is the annular ring shank design, which significantly improves grip strength within the timber, making them ideal for heavy-duty framing and structural fastening. One important caveat to note is that this specific pack size contains only five nails, which is best suited for small-scale repairs or precision tasks rather than large-scale construction projects requiring bulk quantities.

Yes, the sherardised finish provides a durable zinc-iron alloy coating that offers high resistance to rust and environmental elements.
No, these nails are designed specifically for timber construction and wood-to-wood fastening.
This specific package includes 5 nails.
The rings bite into the wood fibers, providing significantly higher withdrawal resistance compared to standard smooth-shank nails.
While not always necessary for softer woods, it is highly recommended when working with hardwoods or thin timber to prevent splitting.
Ensure you are hitting the nail head squarely and using a hammer of appropriate weight; if resistance is too high, consider pre-drilling a pilot hole.
This is common with ring shank nails; always pre-drill a small pilot hole that is slightly smaller than the nail shank diameter to relieve stress.
Due to the annular rings, these nails are designed to resist removal; use a nail puller or crowbar carefully to minimize damage to the surrounding wood.
For optimal installation, ensure you are using a hammer with a face weight appropriate for a 3.35mm diameter nail. Always pre-drill holes if working with hardwoods or near the edge of timber to prevent splitting, as the ring shank design puts additional pressure on the wood grain. Regarding compatibility, these nails are intended for wood-to-wood fastening and are not suitable for masonry or metal surfaces. Store the nails in a dry, cool environment to maintain the integrity of the sherardised coating. While the finish is designed for exterior use, avoid using these in high-acidity environments or treated woods that may react with the zinc-iron alloy coating over time.
