Stainless steel screws

Stainless steel screws are widely used across structural, interior, and exterior applications where corrosion resistance is a key requirement. Common uses include securing metal fixings, timber framing in coastal builds, or cladding panels exposed to moisture. You’ll also see them in roofing, decking, and kitchen or bathroom fittings where exposure to water or humidity is expected. Unlike zinc-plated or galvanised screws, stainless steel screws resist rust without needing surface treatments, which makes them suitable for long-term installations in harsh environments.

Stainless steel screw types include wood screws, machine screws, and self-tapping variants, often available with Pozi, torx, or hex heads for different driving tools. A2 stainless is typically used for general building jobs, while A4 stainless is preferred for marine or highly exposed environments. Some builders also opt for bi-metal screws where extra tensile strength is needed. Most types are available in multiple gauges and lengths to suit both first fix and finishing work.
