304 Stainless Steel Forged Eye Bolts with Threaded Shank — M5 M6 M8 M10 M12

Match the bolt length to your material thickness plus the depth needed for a secure grip. For full-thread versions, the entire shank engages the material. For partial-thread versions (e.g., M8×70 with 40mm thread), the threaded portion should fully pass through your substrate. As a general rule, thread engagement should be at least 1× the bolt diameter — so an M8 bolt typically needs at least 8mm of thread engagement. When in doubt, choose a longer option. Length conversions: 25mm ≈ 1", 50mm ≈ 2", 75mm ≈ 3", 100mm ≈ 3-15/16".

Working load limits vary by size and installation angle. Generally, M5 eye bolts are suited for lighter loads (typically up to ~50–80 kg axial), while M12 bolts can handle significantly more. Always apply a safety factor of at least 4:1 and never exceed the rated working load. For critical load-bearing applications, contact us to confirm ratings for your specific size and use case.

Yes. Made from 304 stainless steel, these eye bolts offer good corrosion resistance in most outdoor environments including rain, humidity, and mild coastal exposure. They are well-suited for garden, patio, pergola, and catenary wire installations. For highly aggressive saltwater or chemical environments, 316 stainless steel is generally recommended — contact us if you need that grade.

These eye bolts use standard ISO metric coarse threads: M5×0.8, M6×1.0, M8×1.25, M10×1.5, and M12×1.75. They are compatible with standard metric hex nuts, coupling nuts, threaded inserts, and T-nuts available at any hardware store. No special tooling or adapters required.

Yes — the threaded shank and forged ring design make these ideal for embedding in resin, concrete, or epoxy. The ring provides a secure anchor point for hanging or rigging after the material cures. Smaller sizes like M5 and M6 are especially popular for resin art, decorative hanging projects, and lightweight structural anchors in cast materials.

"Full thread" means the entire shank length is threaded from tip to ring — ideal for thin materials or when maximum thread engagement is needed. "Thread Xmm" (e.g., Thread 40mm) means only the bottom portion of the shank is threaded; the upper portion is a smooth shank. Partial-thread versions work better for thicker materials where a smooth shank provides a cleaner, more stable fit and prevents the bolt from spinning freely.

Each variant is sold in packs of 1, 2, 5, 10, or 20 pieces of the same size. To mix sizes, simply add multiple variants to your cart. Larger packs offer better per-unit value and are great for contractors, project builders, or keeping a range of sizes on hand.
