Forged Eye Bolts A2 Stainless Steel Full Thread — M6 to M30, 25–390mm

Measure the thickness of the material you are bolting through, then add enough thread engagement — generally at least 1.5× the bolt diameter. For example, an M8 eye bolt typically needs at least 12mm of thread engagement. If you need to pass through a 20mm panel with an M8 bolt, a 35mm (≈1-3/8") or 40mm (≈1-9/16") length is usually appropriate. When in doubt, size up.

Working load limits vary by size and installation angle. As a general guide, an M8 forged eye bolt typically has a vertical working load of around 200–300 kg, while an M12 can handle approximately 500–700 kg vertically. Always derate for angled loads — at 45° the safe working load is typically reduced by 30–50%. Consult the specific load rating for your size before use in safety-critical applications.

Yes. A2 (304) stainless steel offers good corrosion resistance in most outdoor environments and light marine applications. For prolonged saltwater immersion or highly aggressive coastal environments, A4 (316) stainless steel is generally recommended. These bolts are well-suited for garden structures, boat rigging, outdoor signage, and similar applications.

These eye bolts use standard ISO metric coarse thread (DIN 580 / DIN 444 style), which is the most common thread standard in the US and internationally for metric fasteners. They are compatible with standard metric nuts and threaded inserts of the corresponding size.

Forged eye bolts are manufactured by shaping heated steel under high pressure, which aligns the grain structure of the metal and results in significantly greater strength and fatigue resistance compared to stamped (bent wire) eye bolts. For any load-bearing or lifting application, forged eye bolts are the correct choice.

Pack quantity depends on the size selected. Smaller sizes (M6–M10) are available in packs of 5 or 10 pieces. Larger sizes (M12 and above) are available in packs of 1 or 2 pieces. Select your preferred quantity from the Pack Quantity option on this page.

Forged eye bolts are generally suitable for lifting when properly installed vertically and within their rated working load. For overhead lifting, always verify the specific working load limit for your size, ensure the bolt is fully threaded and seated against a load-bearing surface, and use a shoulder-type eye bolt for angled loads. Never exceed the rated capacity.
