M3–M24 Stainless Steel Eye Bolts with Metric Thread — 304 SS Lifting Eyebolt

Match the thread diameter (M3, M4, M6, etc.) to the tapped hole or nut you're threading into. For shank length, choose a length that allows at least 1× the thread diameter of full engagement — for example, an M6 bolt generally needs at least 6mm of thread engagement in the material. Longer shanks (e.g., M6×25mm ≈ 1") are typically used when passing through thicker material or when extra thread engagement is needed for higher loads.

Quick reference: M6×12mm (≈1/2") suits thin panels; M6×25mm (≈1") suits timber framing.

Working load limits vary by thread size and installation method. In general, smaller sizes like M3–M5 are suited for light-duty hanging and craft applications, while M8–M12 are commonly used for moderate rigging and lifting tasks. Larger sizes (M16–M24) are typically used in heavy structural and industrial rigging.

For safety-critical overhead lifting, always verify the rated WLL for your specific size and consult a structural engineer if needed. Do not use these for dynamic shock loads without confirming the rated capacity.

Yes. These are made from 304 stainless steel, which provides good corrosion resistance in most outdoor and mildly marine environments — including garden structures, exterior timber, and coastal-adjacent installations. For prolonged saltwater immersion or highly corrosive chemical environments, 316 stainless steel is generally recommended. For typical outdoor and DIY use, 304 SS performs well without additional coating.

Yes. These eye bolts use standard ISO metric coarse thread (e.g., M6×1.0mm pitch, M8×1.25mm pitch), which is compatible with standard metric nuts, threaded inserts, and tapped holes following ISO 68-1 specifications. They are not compatible with UNC/UNF inch-standard hardware. If you're unsure of your thread standard, check whether your existing hardware is labeled in millimeters (metric) or fractions of an inch (imperial).

Absolutely. Smaller sizes like M3–M6 are commonly used for hanging lightweight items such as pendant lights, planters, picture wires, and cable guides from wood joists, metal framing, or concrete anchors. Always ensure the fastener is threaded into a structurally sound substrate and the load is well within the bolt's rated capacity. For ceiling installations, use a suitable wall plug or anchor if threading into masonry.

Thread the eye bolt fully into a pre-drilled and tapped hole (or use with a matching metric nut and washer) until the shoulder seats flush against the surface. For load-bearing applications, ensure full thread engagement of at least 1–1.5× the bolt diameter. Avoid side-loading a straight-shank eye bolt — if angled loads are expected, use a shoulder eye bolt or swivel eye bolt designed for that purpose. Tighten securely but do not overtorque, which can distort the eye loop.

The size is listed as thread diameter × shank length. So M6×16mm means a 6mm thread diameter with a 16mm (≈5/8") shank length. Available thread sizes range from M3 to M24, with shank lengths from 9mm (≈3/8") to 50mm (≈2"). Select your exact size combination from the variant dropdowns above before adding to cart.
