M12 M14 Stainless Steel Eye Bolts – Threaded Ring for Catenary Wire & Hanging

The shank length should be long enough to pass fully through your mounting material with enough thread exposed to seat a nut and washer securely. As a general rule, allow at least 1.5× the shank diameter of thread engagement in the substrate. For example, an M12 eye bolt typically needs at least 18mm (≈0.71") of thread engagement in steel, or more in softer materials like timber. If you're mounting into a timber beam for a catenary wire anchor, a longer shank — such as 80mm (≈3.15") or 100mm (≈3.94") — is generally preferred for added pull-out resistance.

Working load limits vary by shank diameter and length. As a general reference, M12 A2 stainless eye bolts typically support axial (straight-pull) loads in the range of 500–800 kg depending on the specific geometry, while M14 variants are generally rated higher. However, load ratings drop significantly under angular loading — typically by 25–50% at a 45° angle. For any safety-critical or overhead application, please contact us to confirm the rated capacity of the specific variant you need, and consult a qualified structural engineer.

Yes. A2 (Grade 304) stainless steel offers good resistance to atmospheric corrosion, rain, and moderate salt exposure, making it a common choice for outdoor catenary wire systems, garden structures, and coastal installations. For highly aggressive marine environments — such as direct seawater immersion or heavy salt-spray zones — A4 (Grade 316) stainless is generally recommended for superior chloride resistance. If you're unsure which grade suits your environment, feel free to contact us.

Yes. M12 variants use a standard M12×1.75 coarse metric thread, and M14 variants use M14×2.0 coarse metric thread. Both are compatible with standard DIN 934 hex nuts, DIN 985 nylon-insert locknuts, and other common metric hardware. They are generally compatible with DIN 580 / ISO 3266 eye bolt dimensions. If you need to confirm compatibility with a specific fitting or threaded insert, contact us before ordering.

The choice depends on the load requirements and the thread size of your existing hardware or anchor points. M12 is the more common size for light-to-medium catenary wire runs, hanging planters, and cable management systems. M14 is typically chosen when higher load capacity is needed, or when the mounting structure (such as a steel beam or concrete anchor) is already tapped to M14. If you're matching existing hardware, check the thread diameter of your current fittings before selecting.

A basic catenary wire run between two anchor points requires a minimum of 2 eye bolts — one at each end. Longer runs with intermediate support points, or installations with multiple wire spans, will need more. The 5-piece and 10-piece pack options offer a lower per-unit cost and are a practical choice for multi-span lighting installations, workshop cable runs, or when you want spares on hand. Select the quantity that matches your anchor point count plus one or two extras for contingency.

Yes. The closed circular ring is compatible with wire rope clips, shackles, carabiners, S-hooks, and synthetic rope or cord, provided the ring's internal diameter accommodates the fitting. The closed eye design prevents accidental disengagement of the attached hardware. Always verify that the combined working load of the eye bolt and the connecting hardware does not exceed the lower of the two rated capacities.
