Get your nails tested to meet standards

If you supply nails for timber-framed building projects, getting them officially listed by BRANZ helps demonstrate that they meet New Zealand building standards, giving builders confidence in your product. 

BRANZ tests the nails to assess whether they have:

  • Correct dimensions – to ensure proper performance.
  • Good ductility – so nails bend under pressure instead of snapping.
  • Correct carbon content – to check it's appropriate.
  • Adequate coating (if galvanised) – to protect against corrosion and meet durability standards.

The nail testing process

Getting your nails listed involves a series of checks to make sure they meet the required standards.

Sampling
A random sample is taken from your supplied batch.

Dimensional checks
A selection of nails is measured to ensure they meet the allowable ranges defined in AS 2334-1980.

Bend (ductility) testing
Nails are bent following ASTM F1667 standards and they must bend without cracking.

Carbon content
Nails must contain less than 0.6% carbon by weight, measured in accordance with ASTM F1667-15.

Coating verification (if applicable)
If galvanised, the coating is tested to confirm it meets minimum durability levels (320 g/m²).

If your nails pass all relevant tests, they will be added to the official BRANZ nail listing.

Why get your nails listed?

A BRANZ nail listing confirms your product meets these standards and can be marketed as a compliant fixing solution. This scheme is designed for products that don’t require a full BRANZ Appraisal but still need recognised validation.
