Why Outdoor Screws Matter

Outdoor screws are purpose-built to cope with moisture, UV exposure, temperature changes, and movement in the structure over time. Using indoor-grade fasteners outside can lead to rust, staining, and even structural failure as screws weaken, swell, or shear under load.

Corrosion-resistant materials and coatings — such as A2 and A4 stainless steel, HP coatings, and hot-dip galvanising — help protect the fastener and the surrounding material. This is especially important in decks, fences, cladding, and outdoor framing where fixings are constantly exposed to the elements.

The right outdoor screw not only resists rust but also drives cleanly, grips securely, and reduces splitting in timber and composites. That means fewer callbacks, longer intervals between maintenance, and greater peace of mind on every exterior project.

Outdoor Screw Types

Our outdoor screw range covers the key materials and environments you encounter in exterior work:

  • A2 Stainless Steel Screws: Reliable corrosion protection for general outdoor use. Ideal for decking, cladding, pergolas, and fencing in standard exterior conditions.
  • A4 Stainless Steel Screws: Marine-grade stainless with superior resistance in coastal, wet, or chemically aggressive environments. Perfect for seaside decks, pool areas, and highly exposed fixtures.
  • HP-Coated Screws: Advanced weatherproof coatings that combine strong grip with long-term rust resistance. Suited to treated timber, outdoor structures, and high-humidity or shaded areas.
  • Hot-Dip Galvanised Screws: Heavy-duty zinc coating for structural outdoor applications. Ideal for heavy timber connections, landscaping structures, and external framing where strength and durability are critical.

Applications

Outdoor screws from Craftsman Hardware are suited to a wide range of weather-exposed projects:

  • Decking: Screws with anti-split tips and cutting threads for clean, flush finishes that resist lifting, squeaking, and corrosion over time.
  • Fencing & Gates: Rust-resistant fasteners designed to secure posts, rails, and panels in changing weather conditions without staining or loosening.
  • Cladding & Facades: Screws engineered to hold boards and panels firmly while maintaining an even, attractive finish in windy, wet, or sun-exposed locations.
  • Outdoor Structures: Pergolas, carports, retaining structures, and other exterior builds where structural integrity and long-term appearance both matter.

Selecting the correct outdoor screw for your material, exposure level, and load ensures every external project is built to last from the first fix to the final board.
