A2 Stainless Steel Eye Bolts DIN 580 — M10 M12 M14 M16 M18 M20 M24 Lifting Ring Bolt

Match the thread diameter (M10, M12, M14, M16, M18, M20, or M24) to the tapped hole or nut in your application. For length, measure the grip thickness of the material being fastened — the shank should pass fully through with enough thread engagement, typically at least 1.5× the bolt diameter. For example, an M12 bolt through 20mm (≈3/4") material would generally use a 30–40mm shank. When in doubt, size up.

Working load limits vary by size and configuration. As a general guide, A2 stainless DIN 580 eye bolts typically support in-line (axial) loads ranging from approximately 160 kg for M10 up to 2,000 kg or more for M24. Always consult the manufacturer's rated WLL and apply an appropriate safety factor for your application. Never exceed the rated load.

Yes. A2 (304) stainless steel provides good corrosion resistance for outdoor, coastal, and light marine environments. For highly aggressive saltwater immersion applications, A4 (316) grade is generally recommended. These bolts are well-suited for garden rigging, boat deck fittings, outdoor lifting points, and similar uses where a corrosion-resistant eye bolt is needed.

These eye bolts conform to DIN 580 and use standard ISO metric coarse threads (e.g., M10×1.5, M12×1.75, M16×2.0). They are compatible with standard metric hex nuts, flange nuts, and tapped holes of the corresponding pitch. No special tooling or adapters are required.

DIN 580 eye bolts are designed primarily for in-line (axial) lifting. When a side or angular load is applied, the working load limit is significantly reduced — typically by 25–50% at 45° and more at greater angles. For consistent angular loading, swivel hoist rings or shoulder eye bolts are generally a better choice. In most cases, always rig to minimize the angle from vertical.

Divide the millimeter value by 25.4. Common conversions for this range: 18mm ≈ 11/16", 25mm ≈ 1", 30mm ≈ 1-3/16", 40mm ≈ 1-9/16", 50mm ≈ 2", 60mm ≈ 2-3/8", 80mm ≈ 3-1/8", 100mm ≈ 4", 120mm ≈ 4-3/4", 150mm ≈ 6", 200mm ≈ 7-7/8".

These eye bolts are sold as individual shanks. A matching metric nut and flat washer are generally recommended to distribute the load and prevent pull-through. Nuts and washers are not included and should be sourced separately in the matching metric size and grade. For lifting applications, always ensure the bolt is fully threaded in and the collar (if present) seats flush against the surface.
