A2 Stainless Steel Eye Nuts & Eye Bolts M3–M48 | DIN 582 / DIN 444 | Metric Lifting Hardware

Match the thread size to your existing threaded rod or tapped hole. Common reference points: M6 (≈1/4" nominal) for light fixtures and furniture; M8 (≈5/16") for general rigging and cable anchors; M12 (≈1/2") for medium structural loads; M20 (≈3/4") and above for heavy lifting. Always verify thread pitch before ordering — and when in doubt, size up for a safety margin.

Working load limits vary by size and loading angle. Generally, an M8 A2 stainless eye bolt is typically rated around 0.14–0.2 t axial, while M16 is generally rated around 0.63–1 t axial. Angular loading (e.g., 45°) typically reduces safe working load by 30–50%. Always consult the load table for your specific size and apply an appropriate safety factor. Never exceed the rated working load.

Yes. A2 stainless steel (304 grade equivalent) provides good corrosion resistance in outdoor, humid, and mildly marine environments — a reliable upgrade over zinc-plated hardware for exposed installations. For highly aggressive saltwater or chemical exposure, A4 (316) stainless steel is generally recommended. Contact us if you're unsure which grade suits your environment.

Yes. These use standard ISO metric coarse threads — for example M8×1.25 or M12×1.75 — and are fully compatible with any standard metric threaded rod, stud, or tapped hole of the matching size. They are not compatible with UNC or UNF inch-standard threads. Contact us if you need inch-thread hardware.

An Eye Nut (DIN 582) has an internally threaded body — it threads onto an externally threaded rod or stud protruding from your structure. An Eye Bolt (DIN 444) has an externally threaded shank — it screws into a tapped hole or is secured through a clearance hole with a nut. Choose the eye nut when you have a threaded rod sticking out; choose the eye bolt when you need to install into a hole.

This listing offers 1, 2, 5, 10, or 25 pieces per order. A single piece is ideal for repairs or one-off projects. Packs of 5 or 10 suit most DIY and fabrication jobs. Packs of 25 offer the best per-piece value for contractors, riggers, and fabricators with ongoing metric lifting hardware needs — bulk pricing is reflected in the per-piece cost shown for each quantity option.

These are designed for lifting and rigging applications when used within their rated working load limits and correctly installed. For maximum rated capacity, load the eye axially (in-line with the shank). A 45° angle typically reduces capacity by approximately 30%, and 90° side loading by up to 50%. For critical overhead lifts, always consult a qualified rigging engineer and follow applicable safety standards (e.g., ASME B30.26).
