The Unifix Bright Round Lost Head Nails are designed for professional contractors and DIY enthusiasts who require a reliable, clean-finishing fastener for various woodworking applications. Measuring 65 x 3.35mm, these nails provide a strong and secure hold for structural and decorative timber projects; however, because they lack a protective coating, they are best suited for indoor use where moisture exposure is minimal to avoid oxidation.

No. These are bright finish nails and lack the zinc coating necessary to prevent rust in outdoor or wet environments.
A lost head nail has a small, tapered head designed to be driven beneath the surface of the timber, allowing the hole to be filled and concealed.
These are primarily designed for manual hammering. Using them in pneumatic nail guns may lead to jams or damage to the nail head.
They work best in softwoods and common construction timber. For dense hardwoods, pre-drilling is required.
Yes. It is recommended to prime the filler spot to ensure even adhesion and to prevent any future potential for rust marks to bleed through the paint.
Use a nail punch to drive the head below the timber surface, then cover with matching wood filler.
Reduce the nail gauge or pre-drill a pilot hole slightly smaller than the 3.35mm shank diameter.
Sand the affected area lightly and apply a protective sealant, varnish, or paint to seal the metal from air.
For the best results, ensure you are using a hammer with a smooth face to avoid marring the wood surface. If working with hardwood, it is recommended to pilot drill a small hole first to prevent the timber from splitting. Because these are bright finish nails, avoid using them in external structures like decks or fences. To prevent surface rust, keep the nails in their original packaging in a cool, dry area. If you live in a high-humidity climate, consider a light wipe of machine oil on the nails before long-term storage.
