Lifting Eye Bolts M5 M6 M8 M10 — A2 Stainless Steel Metric Thread, 20mm–150mm

Generally, select a shank length that allows the bolt to pass fully through the material with at least one full thread diameter of engagement beyond the far side. For example, a 20mm (≈3/4") bolt suits thin brackets or plates, while 100mm (≈3-15/16") or longer is typically used for thick timber beams or structural steel sections. Always confirm thread engagement depth before applying any load.

Working load limits vary by thread diameter and shank length. As a general reference, M5 eye bolts typically handle lighter loads (generally under 50 kg WLL), while M10 eye bolts can typically support several hundred kilograms when used vertically with full thread engagement. Always consult a certified rigging engineer and derate for angled lifts. Contact us to confirm the rated capacity for your specific variant before use in safety-critical applications.

Yes. A2 (304) stainless steel provides solid corrosion resistance in most outdoor environments, including coastal and humid conditions. For prolonged saltwater immersion or highly chlorinated environments (such as pool equipment), A4 (316) grade is generally recommended. These bolts are well-suited for outdoor rigging, garden structures, and covered marine applications.

These eye bolts use standard ISO metric coarse thread (M5, M6, M8, M10), compatible with standard metric hex nuts, threaded inserts, and tapped holes following ISO 68-1 / DIN 13 specifications. They are not compatible with UNC or UNF inch-thread hardware. Standard metric nuts in matching sizes are widely available at any hardware store.

These eye bolts are designed for lifting and rigging applications. For overhead lifting, always ensure full thread engagement, use a correctly rated shackle or hook, and apply loads vertically through the plane of the eye. Angled loads significantly reduce safe working capacity — in most cases, a 45° angle reduces WLL by approximately 30%. Consult applicable ASME B30.26 or OSHA guidelines for your specific application and jurisdiction.

Match the thread diameter to your tapped hole or nut size and your load requirements. M5 and M6 are typically used for lighter fixtures, cable management, and small rigging points. M8 is a versatile mid-range size for workshop and construction use. M10 is suited for heavier structural anchoring and load-bearing rigging. When in doubt, size up for a safety margin and confirm with a structural or rigging engineer for critical applications.

Nuts are not included in the standard listing. These eye bolts are sold as individual fasteners in packs of 1, 2, or 5 pieces depending on the variant selected. Standard ISO metric hex nuts in the matching size are widely available and fully compatible.
