A2 Stainless Steel Eye Bolts with Nut — M5 M6 M8 M10 M12 Threaded Ring Screws

Match the thread diameter (M5, M6, M8, M10, or M12) to your tapped hole or nut size. For length, measure the material thickness you're threading through and add enough for the nut to engage fully — typically at least 1× the bolt diameter. For example, an M8 bolt threading through 20mm (≈3/4") of wood generally needs at least 25–30mm (≈1"–1-3/16") of thread engagement beyond the material. When in doubt, size up.

Working load limits vary by size and installation method. As a general guideline, smaller sizes like M5 are typically suited for lighter decorative or light-duty hanging applications, while M10 and M12 eye bolts can handle significantly heavier loads. Always apply an appropriate safety factor — typically 4:1 or higher for overhead lifting — and consult a load table for your specific size. Contact us if you need load data for a particular variant.

Yes. A2 stainless steel (equivalent to 304 stainless) offers good corrosion resistance in most outdoor environments, including coastal and humid conditions. It generally performs well for garden, patio, shed, and light marine applications. For highly aggressive saltwater immersion or chemical environments, A4 (316) stainless steel is generally recommended. If you're unsure, contact us to discuss your specific environment.

These eye bolts use standard ISO metric coarse threads (M5, M6, M8, M10, M12). They are compatible with any standard metric hex nut of the corresponding size. A matching nut is included with each piece. They are not compatible with UNC/UNF (imperial) threads.

Eye bolts can be used for vertical lifting when properly installed and within their rated working load limit. For angled loads, the working load limit is significantly reduced — typically by 25–75% depending on the angle. Always ensure the bolt is fully threaded, the nut is tightened against a load-bearing surface, and the eye is oriented in line with the direction of pull. Consult applicable safety standards (such as ASME B30.26) before any overhead lifting application.

Each order includes the eye bolt(s) and matching hex nut(s) in the quantity you select — 1 Pcs, 5 Pcs, or 10 Pcs. All hardware is A2 stainless steel. No additional fasteners are required for a standard through-bolt installation.

Drill a clearance hole through your material sized to the bolt's thread diameter. Insert the eye bolt from the front, then thread the included hex nut onto the shank from the back side. Tighten the nut firmly against the surface using a wrench — do not over-torque, especially in softer materials like wood. For load-bearing applications, ensure the eye is oriented in line with the direction of pull and that the full thread length is engaged through the material.
