Outdoor Screws : Which Screws are Best for Outdoor Use

Whatever your outdoor projects, whether it's building a decking, installing fencing, or constructing a garden shed. Choosing the right outdoor screws is crucial for ensuring longevity and durability.

Outdoor environments can subject screws to harsh conditions. Rain, temperature fluctuations, and exposure to the sun can corrode screws. Making it imperative to use screws specifically designed for outdoor use.

In this blog, we'll explore the best screws for outdoor applications. Addressing a common question we get asked: "Do you need specific screws for outdoor use?"

Do You Need Specific Screws for Outdoor Use?

Yes you do – if you want your fixings to stand the test of time and the elements.

Using specific screws designed for outdoor use is essential for ensuring the longevity and structural integrity of your outdoor projects. Unlike indoor screws, outdoor screws are engineered to withstand the unique challenges posed by exposure to the elements. Factors such as moisture, increases in temperature, and UV exposure can cause standard screws to degrade rapidly, leading to structural failure and potential safety hazards.

Screw corrosion, or rusting, is caused when moisture reacts with the screw. Exposure to moisture will cause the metals properties to degrade causing rust.  Rust can form under the coating of a screw which can in turn undermine the strength of the screw and breaks down the metal coating.

By investing in screws specifically formulated for outdoor applications, you can rest assured that your projects will withstand the test of time. Even in the harshest weather conditions. Whether you opt for stainless steel, coated, or brass screws will depends on various factors. Factors such as the project requirements, budget considerations, and aesthetic preferences.

Which Screws Are Best for Outdoor Use?

Stainless Steel Screws:

Stainless steel screws are renowned for their exceptional resistance to rust and corrosion. Thus making them an ideal choice for outdoor projects. They are highly durable and can withstand exposure to moisture without compromising their integrity.

Look for screws labelled as "316" or ‘A4’ stainless steel for maximum corrosion resistance, especially in coastal areas where saltwater exposure is a concern.

A4 Screws contain a higher content of nickel and an addition of molybdenum, a white metal that is highly corrosion resistant.
An example of two different types of A4 screw are Stainless Steel Hexagon Head Set Screw and Stainless Steel Pan Head Machine Screw

Coated Screws:

Coated screws, offer enhanced protection against corrosion while also providing additional gripping power. An example of such a coating is the ‘blue ruspert’ coating on masonry screws. These screws are often recommended for use with wood and masonry in environments with high moisture content.

Brass Screws:

Brass screws are prized for their aesthetic appeal and corrosion resistance. While not as durable as stainless steel screws, they are still a viable option for certain outdoor projects, especially those where appearance is a key consideration.
