At BS Fixings, we understand the challenges posed by the great outdoors, especially when it comes to decking, fencing, installing outdoor ironmongery or even assembling garden furniture. That’s why we have curated a range of outdoor screws that not only meet but exceed the demands of any external application, being able to withstand the good-old British weather. In this blog, we’re going to highlight the best screws for outdoor use and our top picks, to help you make the right choice when embarking on your next project.

The Challenges

Outdoor projects are constantly exposed to the elements – rain, wind, sun, and even material treatments can all conspire, weakening your construction over time. Therefore, the choice of screw should factor in features such as corrosion resistance, strength, and ease of use. As we all know, the British climate is notorious for its moisture, which can be detrimental to metal fixtures. Regular, non-treated screws can rust when exposed to repeated wet-dry cycles, leading to structural damage or even complete failure. That’s why you need to purchase specialised outdoor screws.

The Best Types of Outdoor Screws

Our extensive experience and commitment to quality have led us to recommend a few specific types of screws for outdoor use. Each type has been selected based on its material, coating, and design features, which collectively offer the best protection against the weather.

Stainless Steel Screws

Stainless steel is renowned for its corrosion resistance, making it an ideal choice for outdoor projects. Its resilience to rust is due to the addition of chromium, which forms a protective layer on the surface. Stainless steel screws are perfect for areas with high moisture levels or where the screws will be visible, as they maintain their appearance over time.

Galvanised Screws

Galvanised screws are another great option; they are coated with a layer of zinc to protect against rust. These screws are particularly suited for use with treated timber, which can be corrosive to non-galvanised fasteners. This zinc coating will corrode first before the steel, making the fixing last longer.

Decking Screws

Specifically designed for outdoor timber constructions, decking screws are made to resist corrosion from weather exposure and the chemicals found in pressure-treated wood. They come in various materials, including stainless steel and coated carbon steel, each offering different levels of protection and aesthetic appeal.

Spotlight on Exterior-Tite® Csk Pozi Outdoor Screw

Available directly from our extensive online catalogue, we are now proud to offer a fantastic range of outdoor screws from a leader in the industry, Tite-Fix®! Amongst this range is the Exterior-Tite® Csk Pozi Outdoor Screws, which stand out for their exceptional design and performance in outdoor settings. What sets these screws apart is their durable carbon steel construction and Net-coat™ finish (available in black and silver), which improves the screw’s durability against rust and reduces the risk of staining wood or other materials.

These screws also have an innovative Tri-Lock™ TS thread form, that combines a dual and single thread for swift, even, and precise driving, whilst its coarse thread secures a tight grip into timber, preventing loosening over time. Its design allows the head to sit flush with the surface, making it ideal for securing outdoor ironmongery without unsightly protrusions.

Practical Tips for Choosing Outdoor Screws

  1. Consider the environment – assess the typical weather conditions and the type of exposure to elements your project will endure. Coastal areas, for instance, require screws with higher corrosion resistance due to the salty air.
  2. Material compatibility – make sure the screws are compatible with other materials used in your project. Using incompatible screws can lead to galvanic corrosion, as well as damage to both the screw and the material it’s fastened to.
  3. Head type and size – choose a screw head that offers the best control and force distribution for your tools. Pozi and Torx heads are excellent for outdoor fittings because they provide better torque transfer and reduce slip-out.
  4. Length and gauge - ensure the screw dimensions are suitable for the materials’ thickness and the type of load they will bear. Longer screws are generally better for structural projects where strength is most important.
