Measure the full thickness of the material you are bolting through, then add at least 1.5× the thread diameter for adequate thread engagement. For example, M16 eye bolts typically need at least 24mm (about 1") of thread engagement. Available lengths range from 60mm (≈2-3/8") to 200mm (≈7-7/8") so you can match the bolt to your application without excess shank.

Working load limits depend on the direction of pull and installation method. Forged eye bolts generally carry higher rated loads than bent-wire types. For M16 forged eye bolts, in-line (vertical) working loads are typically in the range of 1,000–2,000 kg depending on grade and standard. Always consult a structural engineer and verify the specific load rating for your application before use in safety-critical lifting.

Yes. These are made from 304 (A2) stainless steel, which provides good corrosion resistance in most outdoor and mildly marine environments. For highly aggressive saltwater or chemical environments, 316 (A4) stainless steel is generally recommended. For typical outdoor rigging, hanging, and structural applications, 304 SS performs well.

These eye bolts use standard ISO metric coarse threads (M16 and M18). The included eye nut is matched to the same thread, and they are generally compatible with any standard M16 or M18 metric hex nut or coupling nut. Always confirm thread pitch before mixing fasteners from different sources.

M16 refers to a 16mm nominal thread diameter and M18 to an 18mm diameter. M18 eye bolts are physically larger and typically rated for higher loads. Choose M16 for lighter structural or rigging tasks and M18 when you need greater load capacity or are working with heavier structural members. Check your application's load requirements and the clearance hole size in your material.

Yes. Each unit includes one forged stainless steel eye bolt and one matching eye nut. You can select packs of 1, 2, or 3 sets depending on your project needs.

Forged eye bolts are commonly used in overhead lifting and rigging applications, but safe use requires correct installation (fully seated, shoulder flush with the surface), in-line loading where possible, and verification of the rated working load. Angular loading significantly reduces capacity. Always follow applicable ASME B18.15 or equivalent standards and consult a qualified rigger for safety-critical overhead lifts.
