M5 M6 M8 Forged Eye Bolts with Eye Nut — 304 Stainless Steel, Multiple Lengths

Measure the thickness of the material you are threading through, then add enough length for the eye nut to engage at least 1.5× the bolt diameter in threads. For example, an M6 bolt needs at least 9mm of thread engagement. Available lengths range from 20mm (≈3/4") to 150mm (≈5-7/8") depending on size — select the variant that gives you adequate thread protrusion on the nut side.

Working load limits vary by size and installation angle. Generally, M5 eye bolts are suited for lighter loads, M6 for moderate loads, and M8 for heavier applications. Always apply an appropriate safety factor and never exceed the rated load. Avoid loading at angles greater than 45° from the bolt axis without a rated swivel fitting.

Yes. The 304 (A2) stainless steel construction provides good corrosion resistance for outdoor, humid, and mildly marine environments — including garden structures, patios, and covered boat docks. For highly aggressive saltwater or chemical exposure, 316 (A4) stainless is generally recommended instead.

These use standard ISO metric coarse threads (M5, M6, M8). They are compatible with any standard metric hex nut, coupling nut, turnbuckle, carabiner, or threaded insert of the matching size. They are not compatible with UNC/UNF (imperial) threaded hardware.

Each unit includes one forged eye bolt and one matching eye nut. Pack quantities (1, 3, 5, 10, or 20 pieces) refer to the number of complete bolt-and-nut pairs, so you always get a matched set.

Forged eye bolts are shaped under heat and pressure, producing a denser grain structure and generally higher strength than stamped or bent-wire eye bolts. The eye loop on a forged bolt is solid and continuous, whereas a bent-wire eye bolt has a gap or weld point that is typically weaker. For load-bearing, rigging, or overhead hanging applications, forged is the preferred choice.

Forged eye bolts are commonly used for vertical lifting and rigging when properly rated and installed. Always verify the working load limit for your specific size, ensure full thread engagement (at least 1.5× the bolt diameter), and follow applicable safety standards. Never exceed the rated load, and inspect hardware regularly for wear or corrosion.
