M16–M24 Stainless Steel Lifting Eye Bolts — Reliable Rigging for Every Load

Whether you're rigging machinery in a workshop, securing loads on a job site, or setting up a marine lifting system, finding an eye bolt that won't corrode, strip, or fail under load is non-negotiable. These A2 stainless steel lifting eye bolts are built for contractors, riggers, maintenance crews, and serious DIYers who need dependable hardware that holds up in demanding conditions.

Each pack contains 1, 2, 3, 4, or 5 eye bolts — your choice — in metric thread sizes M16, M18, M20, or M24, with shank lengths ranging from 25mm (≈1.0") to 200mm (≈7.9"). The ring and shank are machined from A2 (304) stainless steel with metric coarse threads conforming to DIN 580 standards. Available in multiple size and length combinations to match your exact application.

Typical use cases include overhead lifting and rigging in fabrication shops, anchor points for fall-arrest systems on construction sites, and tie-down attachment points on trailers and marine vessels — all scenarios where a stainless steel lifting eye screw with a secure metric thread is essential.

🔩 Thread Compatibility: Metric coarse thread (ISO metric), DIN 580 standard — fits standard M16, M18, M20, and M24 threaded holes and nuts.

✅ Key Features of These Stainless Steel Lifting Eye Bolts

  • 🦾 A2 Stainless Steel Construction — Machined from 304-grade stainless steel for strong corrosion resistance in outdoor, coastal, and industrial environments where carbon steel would rust and weaken.
  • 📐 Wide Size Range — Available in M16, M18, M20, and M24 thread diameters with lengths from 25mm (≈1.0") to 200mm (≈7.9"), covering a broad range of rigging and anchoring applications.
  • 🔄 DIN 580 Compatible Design — The forged ring and shank geometry follows DIN 580 specifications, making these eye screws compatible with standard shackles, hooks, and lifting slings used in professional rigging.
  • ⚙️ Metric Coarse Thread for Secure Engagement — ISO metric coarse threads provide reliable thread engagement and resist loosening under vibration, making them well-suited for machinery mounting and dynamic load applications.
  • 📦 Flexible Pack Quantities — Order 1, 2, 3, 4, or 5 pieces per pack so you get exactly what your project needs without overstocking — ideal for both single-point lifts and multi-point rigging setups.
  • 🏭 Smooth Ring Bore for Shackle Compatibility — The eye ring is sized to accept standard shackle pins and hooks, allowing quick connection to chain, wire rope, or synthetic slings without modification.

❓ Frequently Asked Questions

How do I choose the right length for my lifting eye bolt?

Generally, the shank should engage at least 1.5× the bolt diameter of thread into the receiving material. For example, an M16 bolt (16mm / ≈5/8" diameter) typically needs at least 24mm of thread engagement. Choose a longer shank when working with softer materials like aluminum or timber. For through-bolt applications, match the shank length to the material thickness plus any washer or nut stack height.

What load capacity can these lifting eye bolts handle?

Load capacity varies by thread size and lifting angle. In most cases, M16 eye bolts are rated for vertical loads in the range of 1,000–2,000 kg, while M20 and M24 sizes typically handle higher loads. Always verify the rated Working Load Limit (WLL) for your specific size and never exceed it. Contact us to confirm the WLL for your chosen variant.

Are these eye bolts suitable for outdoor or marine use?

Yes. A2 (304) stainless steel provides strong resistance to rust, moisture, and mild corrosive environments, making these eye bolts generally suitable for outdoor, coastal, and light marine applications. For highly aggressive saltwater or chemical environments, A4 (316) stainless steel is typically recommended for longer service life.

What thread standard do these eye bolts use — will they fit my equipment?

These lifting eye bolts use standard ISO metric coarse threads, conforming to DIN 580 specifications. They are designed to fit standard metric threaded holes and are compatible with metric nuts, shackles, and rigging hardware. If you need to confirm the thread pitch for a specific size, please contact us before ordering.

Can I use these eye bolts at an angle instead of straight up?

Lifting eye bolts are designed for vertical (0°) lifting. When used at an angle, the Working Load Limit is significantly reduced — typically by 25–75% depending on the sling angle. For angled or multi-leg lifts, swivel hoist rings or properly rated shackles are generally recommended. Always consult a qualified rigger for non-vertical lifts.

How do I decide between M16, M18, M20, and M24?

Choose the thread diameter based on your load requirement and the existing threaded hole in your application. M16 is well-suited for light to medium loads and is the most common size for general rigging. M18 and M20 are typically used for medium to heavy loads, and M24 is designed for heavy-duty industrial lifting. Always match the bolt size to the rated WLL for your specific lift scenario.

Do these come with a nut or washer included?

Each pack contains the specified quantity of eye bolts only. Matching metric nuts and washers are not included by default. If you need a complete fastener set or matching hardware, please contact us or browse our related listings for compatible components.
