M8 M10 Stainless Steel Eye Bolts A2 — Threaded Ring Screws for Catenary Wire & Hanging

Match the shank length to the thickness of the material you're threading into, plus enough engagement depth for a secure hold — generally at least 1.5× the bolt diameter. For M8 bolts, that's typically 12mm (about 1/2") of thread engagement minimum. For M10, aim for at least 15mm (≈5/8"). Available lengths in this listing run from 20mm (≈3/4") to 150mm (≈5-7/8"), so you can match the shank to your specific substrate thickness.

Working load limits vary by size, installation angle, and substrate. M8 eye bolts generally support a vertical working load of around 100–200 kg, while M10 bolts typically handle 150–300 kg under ideal conditions. Loads applied at an angle significantly reduce capacity. Always apply an appropriate safety factor and consult a structural engineer for critical or overhead load-bearing applications.

Yes — A2 (304) stainless steel offers good corrosion resistance for most outdoor environments, including rain, humidity, and light coastal exposure. For prolonged saltwater immersion or highly aggressive marine environments, A4 (316) stainless steel is generally recommended. These bolts are well-suited for garden catenary wire systems, outdoor signage, and covered exterior installations.

These use standard ISO metric coarse thread — M8 (1.25mm pitch) and M10 (1.5mm pitch). They are compatible with standard metric nuts, coupling nuts, threaded rod, threaded inserts, and any pre-tapped hole following the ISO metric coarse thread standard. No special adapters are needed for typical hardware store accessories.

Yes — eye bolts are a common and effective anchor point for catenary wire and festoon lighting installations. Thread the bolt into a structurally sound anchor point (solid timber, masonry with appropriate anchor, or steel), then attach your wire rope or cable using a wire rope clip, carabiner, or turnbuckle through the eye. Ensure the combined wire tension and fixture weight does not exceed the bolt's working load rating.

This listing offers 1, 2, 5, 10, or 25 pieces per order. For a simple two-point catenary wire run, 2 pieces is typically sufficient. For longer runs with intermediate anchor points, or for workshop cable management grids, 10 or 25-piece packs offer better per-unit value. We recommend ordering a couple of spares for longer projects.

For most DIY applications, you can hand-tighten smaller eye bolts or use a screwdriver or rod threaded through the eye for additional torque. For larger sizes (M10) or high-load applications, a torque wrench with an appropriate adapter is recommended to ensure consistent, proper installation. Always pre-drill a pilot hole in wood to the correct diameter before threading in the bolt.
