A2 Stainless Steel Eye Bolts M5–M24 | Threaded Ring Screws for Catenary Wire & Hanging

Match the thread diameter (M5, M6, M8, etc.) to your tapped hole or nut size. For length, measure the thickness of the material you're threading into and ensure the threaded portion is at least 1–1.5× the bolt diameter for secure engagement. For example, an M8 bolt going into 30mm of timber generally needs at least 20–25mm (≈1") of thread engagement. When in doubt, choose a longer bolt — you can always use a nut to control seating depth.

"Fully Threaded" means the thread runs the entire length of the shank, giving you maximum flexibility for depth of engagement. Partial thread options (e.g., 40mm or 50mm threaded length) have a smooth unthreaded shank section above the thread, which is useful when you need the bolt to pass through a clearance hole before threading into a nut or tapped section. Choose partial thread when you need a specific grip length or are passing through multiple layers of material.

Yes. A2 stainless steel (304 grade) provides strong resistance to atmospheric corrosion, moisture, and mild chemical exposure, making these eye bolts well-suited for outdoor use including garden structures, pergolas, catenary wire installations, and covered marine environments. For highly aggressive saltwater or chlorinated environments, A4 (316) stainless steel is generally recommended for longer-term performance.

These are ISO metric coarse-thread eye bolts (M5 through M24). They are compatible with any standard metric nut or tapped hole of the matching diameter. For example, M8 uses a 1.25mm pitch, M10 uses 1.5mm pitch — all standard coarse metric, available at any hardware store.

Load capacity varies by thread size, installation depth, and base material. Generally, a properly installed M8 A2 stainless eye bolt can handle in-line loads of several hundred pounds, while M16–M24 sizes are rated for significantly higher loads. These eye bolts are designed for in-line (vertical) loads only — angular loads significantly reduce safe working capacity. Always verify the working load limit (WLL) for your specific size before use in load-bearing applications.

Yes — these eye bolts are specifically suited for catenary wire hanging applications such as outdoor string lights, garden wire runs, and cable suspension systems. The closed eye ring accepts wire rope clips, carabiners, and S-hooks. For catenary wire, M6 or M8 sizes are typically sufficient for light decorative loads, while M10–M12 are generally used for heavier cable runs or structural wire tensioning.

The 1pcs option is ideal for single anchor points or testing a size before committing. The 10pcs option offers a lower per-unit cost and is suited for projects requiring multiple anchor points — such as running a full catenary wire system, hanging multiple fixtures, or installing a series of cable guides across a pergola or fence line.
