When should you use galvanised screws and other outdoor screws?

September 30th, 2013

Galvanised screws and nails are zinc coated nails that have undergone a galvanisation process.

This process means the nails have a protective barrier which makes them resistant to rust and corrosion. Such properties make galvanised nails perfect for outdoors projects, and are often used by homeowners and builders alike in locations that could be damp.

Projects such as roofing, fencing and decking are all perfect applications for using galvanised nails as they wont rust when it rains (a test they stand up to on a weekly basis in the UK).

The zinc coating on nails treated in this way acts as a sacrificial anode, and will decay before the metal inside. However, galvanised nails created through electroplating (these are often bright and shiny) are not a good choice when used with certain redwoods or treated lumbers as they will leave black streaks around the nail. Mechanically galvanised nails should be used with these wood types, but both will still offer the same weather protection.

Stainless steel decking screws are another great option when it comes to outdoors screws and nails, as well as stainless steel screws. Both have properties that make them weather resistant, and are especially hardy against rain.

Here is a list of great outdoors nails and screws, their properties and best applications:
