304 Stainless Steel Ring Eye Bolt & Eye Nut — M3 to M36, Screws & Nuts

Match the thread diameter (M3, M6, M10, etc.) to the tapped hole or nut size in your application. As a general rule, the larger the load, the larger the thread size you should use. For example, M6 (≈1/4") is commonly used for light rope anchoring, while M12 (≈1/2") and above are typically used for heavier rigging. When in doubt, size up — a larger eye bolt generally provides a higher working load limit.

An eye nut has internal threads and is designed to thread onto an externally threaded stud or bolt — it acts as the nut in the assembly. An eye screw (eye bolt) has external threads and is designed to be screwed directly into a tapped hole, wood, or a threaded insert. Choose based on your mounting configuration.

The working load limit (WLL) varies by thread size and the angle of the applied load. In-line (vertical) loading generally allows the highest WLL, while angular loading reduces it significantly. For specific load ratings by size, please contact us to confirm before use in any safety-critical application. As a general reference, smaller sizes (M3–M6) are typically suited for light-duty use, while larger sizes (M12 and above) are generally used for heavier rigging tasks.

Yes — 304 stainless steel offers good resistance to rust and oxidation, making it suitable for outdoor, garden, and light marine use. However, in highly corrosive environments (such as direct saltwater immersion or chlorinated pools), 316 stainless steel is generally recommended for longer service life. For most outdoor DIY and coastal applications, 304 SS performs well.

Yes. These eye bolts and eye nuts are machined to standard ISO metric thread specifications. They are compatible with standard metric nuts, bolts, threaded rod, and inserts. The thread pitch follows the standard (coarse) metric pitch for each diameter, which is the most common pitch used in general hardware applications in the US and internationally.

If you need a single replacement or are testing a fit, the 1-piece option works well. For paired applications (such as two anchor points for a hammock or swing), the 2-piece option is convenient. For larger projects — rope systems, cable runs, or workshop rigging setups — the 5- or 10-piece packs typically offer better value per unit. Select your quantity using the "Quantity (pcs)" variant selector above.

These eye bolts are generally suitable for light-to-medium suspension and rigging tasks. For certified overhead lifting in industrial or occupational settings, you should use eye bolts that are rated and certified to ASME B18.15 or equivalent standards. If you are unsure whether these meet your specific safety requirements, please contact us or consult a qualified engineer before use.
