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.

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.

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.

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.

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.

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.

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.
