M10 M12 M14 Stainless Steel Eye Bolt & Eye Nut Set — A2-304, Threaded Lifting Ring

Generally, the shank should be long enough to pass fully through the material with at least one full diameter of thread engagement beyond the surface. For example, an M10 bolt threading into 20mm of material typically needs a shank of at least 30mm (≈1.2"). When in doubt, choose the next size up. Convert mm to inches by dividing by 25.4 — so 50mm ≈ 2.0", 100mm ≈ 3.9", 150mm ≈ 5.9".

Working load limits vary by size and application angle. As a general guideline, M10 eye bolts typically support 200–400 kg vertically, M12 around 320–600 kg, and M14 around 500–900 kg. Side-loading significantly reduces capacity. Always apply a safety factor and consult a structural engineer for critical lifting applications.

Yes. A2-304 stainless steel offers good corrosion resistance in most outdoor environments, including rain, humidity, and light coastal exposure. For prolonged saltwater or harsh marine conditions, A4-316 grade is generally recommended. These fasteners are well-suited for covered outdoor structures, freshwater boat rigging, garden hardware, and general exterior applications.

These use standard ISO metric coarse threads (M10, M12, M14), compatible with any standard metric nuts, bolts, and threaded inserts of the matching size. They are not compatible with UNC/UNF inch-standard fasteners. If you're unsure, check your existing hardware with a thread gauge before ordering.

Yes. The eye bolt and eye nut in the same diameter share the same metric thread pitch, so they can be used together. A common configuration is threading the eye nut onto the protruding shank of an eye bolt to lock it in place through a panel or beam, creating a secure double-anchor point.

The 1 Pcs option is ideal for single-point anchors, replacements, or testing fit before a larger order. The 5 Pcs pack offers better per-unit value for projects requiring multiple attachment points — such as rigging a tarp, hanging a hammock, securing equipment in a workshop, or outfitting a trailer with multiple tie-down rings.

An eye bolt has a threaded shank that inserts into a tapped hole or passes through a surface and is secured with a nut — the ring end faces outward for attaching hooks, ropes, or cables. An eye nut has an internal thread and is screwed onto an existing bolt or threaded rod, with the ring on top. Both serve as anchor points; the right choice depends on whether you're threading into a hole or onto a stud.
