Measure the full thickness of the material you are bolting through, then add typically 1.5× the thread diameter to ensure sufficient thread engagement on the nut side. For example, for M20 through a 50mm (≈2") plate, a 70mm (≈2.76") bolt generally provides adequate grip. When in doubt, size up to the next available length.

Working load limits depend on the application angle and installation method. Forged eye bolts generally offer significantly higher load ratings than bent-wire types. For vertical straight-pull applications, M20 forged eye bolts typically support several hundred kilograms; M24 more so. Always consult a structural engineer for safety-critical lifting applications and derate for angled loads per ASME B30.26 or equivalent standards.

Yes. The 304 (A2) stainless steel construction provides strong resistance to rust and atmospheric corrosion, making these eye bolts well-suited for outdoor, coastal, and light marine environments. For fully submerged saltwater applications, 316 (A4) stainless is generally recommended for superior chloride resistance.

These eye bolts use standard ISO metric coarse threads — M20 and M24. The included eye nut is matched to the same thread pitch, so no additional hardware is needed for a complete through-bolt assembly. They are compatible with standard metric hex tooling and metric clearance holes.

Forged eye bolts are manufactured from a single piece of steel shaped under heat and pressure, resulting in a continuous grain structure with no weld seam at the eye. This generally produces a stronger, more reliable fastener compared to bent-wire or welded-eye designs, especially under dynamic or angled loads. For any load-bearing application, forged is the preferred choice.

Forged eye bolts are commonly used in rigging and lifting setups. However, always verify the working load limit for your specific size and application angle, use a properly rated shackle or hook, and follow applicable safety standards such as ASME B30.26 in the US. Never exceed the rated load, and inspect fasteners regularly for signs of wear or deformation.

Yes. Each set includes one forged eye bolt and one matching eye nut of the same thread size. You can order 1 or 2 sets per purchase using the quantity selector above. The eye nut allows you to create a through-bolt assembly or attach rigging hardware to both ends.
