A2 Eye Bolts 304 Stainless Steel Hook Ring Screw — M3 M4 M5 M6 M8 M10 M12 M16 M18 M24

Match the thread size (M3–M24) to your tapped hole or nut. For shank length, measure the material thickness you're threading into and allow for adequate thread engagement — generally at least 1.5× the bolt diameter. For example, an M6 bolt typically needs at least 9mm of thread engagement. Lengths on this listing range from 9mm (≈3/8") to 50mm (≈2"). When in doubt, size up on length — you can always add a nut to take up extra thread.

Working load limits vary by thread size and installation method. As a general guide, a properly installed M6 A2 stainless eye bolt can typically handle 100–150 kg vertically; M10 generally handles 300–500 kg. Always apply an appropriate safety factor (typically 4:1 or higher for lifting) and never exceed the rated load. Contact us to confirm specifications for your specific application before use in load-bearing situations.

Yes. A2 (304) stainless steel offers good corrosion resistance in most outdoor environments, including light coastal exposure. For highly aggressive saltwater or chemical environments, A4 (316) stainless is generally recommended. These bolts are well-suited for garden, deck, pergola, and general outdoor rigging applications. Regular rinsing with fresh water helps maintain appearance in coastal settings.

These eye bolts use standard ISO metric threads (M3–M24), compatible with standard metric nuts, threaded inserts, and tapped holes. They are not compatible with UNC/UNF inch threads. If your existing hardware uses imperial sizing (e.g., 1/4"-20 or 3/8"-16), these bolts will not fit without an adapter.

These eye bolts are suitable for light-duty lifting and rigging when properly installed and within rated load limits. For critical overhead lifting applications, always verify the working load limit, use a certified rigging component, and apply the appropriate safety factor. Note that straight-shank eye bolts are generally rated for vertical (axial) loads only — for angular loads, a shoulder-type eye bolt is typically preferred. Contact us to confirm suitability for your specific rigging setup.

You can choose from 1, 2, 5, or 10 pieces per order using the Amount selector above. Buying in larger quantities offers a lower per-piece cost. If you need quantities beyond 10 pieces, please contact us — we may be able to accommodate larger orders.

A2 304 stainless steel is highly resistant to rust and surface staining under normal conditions. In prolonged exposure to chlorides (salt spray, pool chemicals), minor surface discoloration may occur over time. Regular rinsing with fresh water and occasional wiping with a stainless steel cleaner helps maintain appearance in demanding environments.
