Lifting Eye Nuts & Eye Bolts M3–M14 | A2 Stainless Steel Rigging Fasteners

Match the thread size to your existing bolt, threaded rod, or tapped hole. The "M" number refers to the nominal thread diameter in millimeters — for example, M6 has a 6mm (≈1/4") thread diameter, and M10 has a 10mm (≈3/8") thread diameter. As a general rule, smaller sizes like M3–M5 are typically used for light-duty hanging and securing tasks, while M8–M14 are generally suited for heavier rigging and structural applications. When in doubt, size up for a safety margin.

Working load limits vary by size and how the fastener is installed. In general, smaller sizes (M3–M5) are typically rated for light loads in the range of a few kilograms, while larger sizes (M10–M14) can generally handle significantly heavier loads. Always apply an appropriate safety factor (typically 4:1 or higher for lifting) and never exceed the rated working load. Contact us to confirm load ratings for your specific size and application.

Yes — A2 stainless steel (304 grade) offers good corrosion resistance for outdoor, humid, and mildly marine environments. It performs well in rain, moisture, and general atmospheric exposure. However, for highly aggressive saltwater immersion or chemical environments, A4 stainless steel (316 grade) is generally recommended for superior chloride resistance. These are a solid choice for most outdoor rigging and garden hardware applications.

These fasteners use standard ISO metric coarse threads, following DIN/ISO specifications. They are compatible with standard metric threaded rods, bolts, and tapped holes of the corresponding size. M3 through M14 are the most common metric sizes used in construction, machinery, and rigging hardware across North America and internationally.

An Eye Nut has an internal (female) thread — you screw it onto the end of a threaded rod or bolt, and the loop provides your attachment point. An Eye Bolt has an external (male) thread — you screw it into a tapped hole or through a surface and secure it with a nut, and the loop provides your attachment point. Choose an eye nut when you need to cap a threaded rod; choose an eye bolt when you need to anchor into a surface.

These eye nuts and eye bolts are commonly used in light-to-medium rigging, hanging, and securing applications. For certified overhead lifting — particularly in industrial or workplace settings — regulations typically require hardware that is specifically rated, tested, and marked with a working load limit by the manufacturer. Contact us to confirm the specifications for your size before using in any overhead lifting application, and always consult applicable safety standards (such as ASME B30 or OSHA guidelines).

Yes — you can order as few as 1 piece. Simply select your preferred quantity (1, 2, 3, 5, or 10 pieces) from the QTY option on this page. Ordering larger quantities reduces the per-piece cost, which is useful if you're outfitting a full rigging project or want spares on hand.
