Sherardised Annular Ringshank Nails | Multiple Sizes

Ringshank nails are the go-to fixing where standard smooth-shank nails simply don’t hold well enough. The annular rings cut into the surrounding timber fibres as the nail is driven, locking it in place far more effectively than a plain wire nail. These sherardised ringshank nails are designed for structural and medium-duty timber applications where grip matters and moisture resistance is required.

Sherardising is a zinc-diffusion coating process that bonds zinc into the surface of the steel at a molecular level. The result is a uniform, hard-wearing coating that resists corrosion better than a standard galvanised nail and performs reliably in service class 2 conditions. These nails conform to Eurocode 5, which means they’re an approved choice for structural timber connections in engineered and frame construction. If your project needs a documented fixing, these are worth having on site.

Where Sherardised Ringshank Nails Are Used

These nails are used across a wide range of timber construction work. Roof truss assembly, floor deck fixing, timber frame construction, cladding and boarding, and fencing are all common applications. The ringshank profile is particularly useful anywhere the fixing will experience withdrawal forces, such as decking boards that cup slightly as they dry, or cladding that’s subject to wind load. In short, anywhere a smooth-shank nail has a habit of working loose over time.

Service class 2 compliance means these nails are suitable for use in covered, humid environments such as unheated buildings, agricultural structures, and external-facing timber that remains dry in service but is exposed to higher moisture levels during or after construction. They are not intended for permanently wet or submerged applications.

Size and Pack Options

These ringshank nails are available in three sizes: 40 x 2.65mm, 50 x 2.65mm, and 65 x 3.35mm. The 40mm and 50mm nails share the same gauge and suit lighter structural work and boarding. The 65 x 3.35mm is the heavier option for thicker timber sections and more demanding fixings. Pack options include 0.5kg, 1kg, and 2.5kg in both TIMbag and TIMtub formats, so whether you need a small supply for a single job or a bulk quantity for a larger site, there’s a practical pack to suit.

TIMtub packaging is particularly handy on site. The rigid tub keeps nails organised and accessible in a nail bag or toolbox without the bag splitting at an inconvenient moment. Small detail, but anyone who’s scattered a kilo of nails across a roof deck will appreciate it.

For reliable holding power, corrosion resistance, and compliance with structural timber standards, these sherardised ringshank nails are a sensible choice. Priced for trade use and available in practical pack sizes, they’re a straightforward stocking item for builders, roofers, and carpenters who need a fixing that does what it’s supposed to.
