Stainless Steel Eye Bolts & Hook Bolts — Wood Thread, M5–M16, A2 304

Match the bolt diameter to your load and timber thickness. M5 (≈3/16") and M6 (≈1/4") are generally suited for lighter decorative hanging like wind chimes or small bird feeders. M8 (≈5/16") through M12 (≈15/32") cover most medium-duty workshop and garden rigging. M14 and M16 (≈9/16"–5/8") are typically used for heavier structural applications such as rope swings or pulley systems. When in doubt, size up for a safety margin.

Load capacity varies by size and duty rating. Generally, M5 is suited for lighter loads (typically up to 50–80 kg in ideal conditions), while M16 heavy-duty versions can handle significantly more. Always consult a structural engineer for safety-critical or overhead load applications, and never exceed the rated working load limit. Contact us to confirm specific load ratings for your chosen variant.

Yes. A2 (304) stainless steel offers strong resistance to rust, oxidation, and general atmospheric corrosion, making these bolts well-suited for outdoor gardens, decks, pergolas, and light coastal environments. For highly aggressive saltwater or chemical exposure, A4 (316) stainless steel is generally recommended. In most outdoor residential applications, A2 performs reliably for many years.

No. These bolts feature a wood thread (also called lag thread or coarse wood screw thread), designed to be driven directly into timber without a nut. They are not compatible with standard metric hex nuts. If you need a machine thread version for use with nuts or metal substrates, please contact us to confirm availability.

Choose the Eye type when you need a fully closed loop — ideal for attaching ropes, cables, carabiners, or S-hooks where the connection must stay secure and cannot accidentally slip out. Choose the Hook type when you need quick attachment and detachment, such as hanging planters, lanterns, bird feeders, or decorative items that you swap out seasonally.

Pre-drill a pilot hole slightly smaller than the bolt's shank diameter to prevent wood splitting — this is especially important for M8 and larger sizes. Thread the bolt in by hand first to confirm alignment, then use a screwdriver or a rod inserted through the eye or hook to apply torque. Do not overtighten, as excessive force can strip the wood fibers and reduce holding strength.

Light versions typically feature a thinner shank and a smaller eye or hook ring, suited for lighter decorative or low-load applications such as hanging small wind chimes or picture wires. Heavy versions generally have a thicker shank and a larger, more robust ring for higher load-bearing tasks like rigging ropes, supporting hanging baskets, or workshop pulley systems.
