A2 (304) stainless steel contains chromium and nickel, giving it inherent corrosion resistance without a surface coating. It performs well in wet, outdoor, and coastal environments where the coating on galvanised steel could eventually wear or chip. Galvanised eye screws have a zinc coating applied over mild steel, which provides adequate protection for sheltered or indoor use at a lower cost per piece. If the fastener will be exposed to rain, humidity, or salt air, choose A2 stainless. For dry indoor applications, galvanised is a practical choice.

Thread diameter should be matched to the load the eye screw will carry and the substrate it threads into. Smaller diameters (M3–M4) suit lightweight hanging tasks such as picture wire or small cable runs in thin timber. Mid-range diameters (M5–M6) handle moderate loads in thicker timber or metal panels. Larger diameters (M8–M12) are appropriate for structural rigging, heavy cable management, or applications where the eye must resist significant pull-out force. Always pre-drill a pilot hole slightly smaller than the thread diameter when installing into wood.

The shank length determines how deep the threaded portion engages with the substrate. For wood, a general rule is to engage at least 2–3× the thread diameter in depth for adequate pull-out resistance — for example, an M6 eye screw should engage at least 12–18 mm into the timber. For metal panels or threaded inserts, match the shank length to the material thickness plus any required protrusion. Longer shanks (50–100 mm) are suited to thick timber beams or applications where the eye must extend through a panel and be secured with a nut on the reverse side.

The A2 stainless steel variants are suitable for outdoor use including garden, patio, and sheltered marine environments. A2 (304) stainless resists rust from rain and humidity effectively. For full saltwater immersion or highly aggressive marine environments, A4 (316) stainless is typically recommended — if your application involves direct seawater contact, contact us to confirm suitability. Galvanised variants are not recommended for prolonged outdoor exposure where the zinc coating may degrade.

Yes. The threads conform to standard metric pitch specifications, so they are compatible with standard metric hex nuts, wing nuts, and threaded inserts of the corresponding diameter. This makes them straightforward to use in through-bolt configurations where a nut is applied to the protruding end of the shank for a secure, removable connection.

Load capacity depends on thread diameter, shank engagement depth, substrate material, and the direction of the applied load (axial pull vs. lateral shear). Specific working load limit (WLL) data is not published for these fasteners as they are general-purpose hardware rather than rated lifting components. For safety-critical load-bearing applications such as lifting or fall-arrest systems, use rated and certified rigging hardware. For decorative hanging, cable routing, and light rigging tasks, select a diameter appropriate to the load with a conservative safety margin.

The 1-piece option is ideal for a single repair or replacement where you need an exact size match. The 10-piece pack suits small projects such as fitting a trellis, hanging a set of shelves, or wiring a cabinet. The 50-piece pack offers the best per-unit value for bulk installations, production runs, or workshop stock where you regularly use the same size. All pack sizes ship the same fastener — only the quantity and per-unit price differ.
