Duplex Nails

A duplex nail is a type of nail that features a double-headed design. Unlike traditional nails with a single head, duplex nails have heads on both ends of the nail body. This unique design makes them versatile and suitable for certain applications where temporary fastening or easy removal is desired. The double-headed configuration of duplex nails allows them to be easily inserted and removed using minimal tools. They are often used in temporary construction work, formwork, concrete pouring, and woodworking projects where the nail needs to be taken out without causing significant damage to the materials being fastened.

  • What is a duplex nail?

    Duplex nail is a double-headed nail which is its distinctive feature.

  • 2. What is duplex nail used for?

    Duplex nails are most used in temporary construction, such as building wooden scaffolding, formwork, or temporary wood braces where nail removal is required.

  • 3. What duplex nail sizes I should use?

    The accepted rule of thumb is the nail length should be 2 times the thickness of the wood you are nailing through. Thus, for 25 mm. thick material, you would use 50 mm. nail and for 50 mm. thick material, you’d use a 100 mm. nail.

  • 4. What are duplex nail finishing types?

    Bright nails are not coated with a protective finish layer which means they are more vulnerable to outdoor conditions.

    Electro-galvanized (white) nails have a 12μ layer of zinc which offers corrosion protection. They are generally used in areas where minimal corrosion protection is needed.

    Electro-galvanized (yellow) nails offer the same corrosion protection as white galvanized nails the only difference is the color.
