Are these eye bolts suitable for outdoor or marine use?

Yes. A2 (304) stainless steel offers good corrosion resistance for outdoor, coastal, and light marine environments. For prolonged saltwater immersion, A4 (316) grade is generally recommended. These are well-suited for garden, workshop, and covered outdoor applications.

What thread standard do these eye bolts use?

These use standard ISO metric coarse thread (e.g., M6×1.0, M8×1.25, M10×1.5). They are compatible with standard metric nuts, threaded inserts, and tapped holes following ISO 261/262 specifications.

Can I use these for vertical lifting only, or also for angled loads?

Standard eye bolts (non-shoulder type) are designed for vertical, in-line loads. For angled lifts, the working load must be significantly derated — typically 25–50% depending on the angle. For frequent angled lifting, a shoulder eye bolt or swivel hoist ring is generally recommended.

How do I convert the bolt length from mm to inches?

Divide the mm value by 25.4. For example: 25mm ÷ 25.4 ≈ 1.0" and 40mm ÷ 25.4 ≈ 1.57". The shank length listed in the variant name refers to the threaded portion only, not the overall height including the eye ring.

Lifting Eye Bolts A2 Stainless Steel — Reliable Metric Rigging Hardware from M3 to M24

Whether you're rigging a workshop hoist, securing a load for transport, or hanging heavy equipment from a ceiling beam, a corroded or undersized eye bolt is a liability you can't afford. Contractors, riggers, fabricators, and serious DIYers need a fastener that holds its rated load and resists rust — even in damp or outdoor conditions.

Each listing covers a single A2 (304) stainless steel lifting eye bolt with a fully threaded metric shank. Sizes run from M3 × 9mm (≈3/8") up to M24 × 40mm (≈1-9/16"), with shank lengths ranging from 9mm (≈3/8") to 50mm (≈2"). The eye ring is formed from the same A2 stainless bar stock, giving you a one-piece construction with no weld seam at the ring base. Available in pack quantities of 1, 2, 3, 5, 10, or 20 pieces per order.

Typical use cases include overhead lifting points in garages and machine shops, anchor points for rope, cable, or chain in marine and outdoor rigging, suspension hardware for lighting rigs and display fixtures, and securing tie-down points on trailers and equipment frames — all applications where a stainless metric eye bolt with a reliable thread engagement is the right call.

🔩 Thread Compatibility: ISO metric coarse thread (M3–M24). Fits standard metric nuts, threaded inserts, and tapped holes per ISO 261/262. Not compatible with UNC/UNF inch threads.

✅ Key Features of These Stainless Steel Metric Lifting Eye Bolts

🦾A2 Stainless Steel Construction — Grade 304 stainless provides solid corrosion resistance for outdoor, coastal, and workshop environments where carbon steel would rust quickly.
📏Wide Metric Size Range — Available from M3 × 9mm up to M24 × 40mm, covering the most common metric lifting eye bolt sizes used in light to medium industrial rigging.
🔗One-Piece Forged Ring Design — The eye ring and shank are formed from a single piece of bar stock, eliminating the weak point of a welded or brazed ring joint under load.
🧵Full-Length Metric Coarse Thread — The shank is threaded along its full usable length, giving you maximum thread engagement depth and flexibility in installation thickness.
📦Flexible Pack Quantities — Order 1 to 20 pieces per size, so you can grab a single replacement or stock up for a project without paying for more than you need.
🏭Broad Application Compatibility — Suited for overhead lifting points, rope and chain anchor hardware, suspension rigging, and tie-down anchor bolts across workshop, marine, and construction settings.

⚠️ Safety Note: Always verify the working load limit for your specific size before use in overhead or safety-critical lifting. Derate for angled loads. These are standard (non-shoulder) eye bolts — for frequent angled lifts, a shoulder-type or swivel hoist ring is recommended.

❓ Frequently Asked Questions

How do I choose the right eye bolt size for my application?

Match the thread diameter to your tapped hole or nut size — M6 fits a 6mm threaded hole, M10 fits a 10mm hole, and so on. Shank length should provide at least 1.5× the thread diameter of engagement depth into the material. For example, an M8 bolt generally needs at least 12mm of thread engagement. When load requirements are close to the limit, go one size up for a safety margin.

What is the working load limit of these eye bolts?

Working load limits vary by size and are typically specified for vertical, in-line loading only. As a general reference, M6 eye bolts typically handle around 100–150 kg vertically, M10 around 300–400 kg, and M12 around 500–700 kg. These figures are approximate — always consult a rated load table for your specific size and application. Contact us to confirm the rated capacity for your chosen size.

Are these suitable for outdoor or marine environments?

A2 (304) stainless steel offers good corrosion resistance for outdoor, coastal, and light marine use — far better than zinc-plated or plain steel alternatives. For prolonged saltwater immersion or aggressive chemical environments, A4 (316) grade is generally recommended. These are well-suited for garden structures, covered outdoor rigs, workshops, and boat deck hardware in non-immersed applications.

What thread standard do these use — are they compatible with standard metric nuts?

Yes. These use ISO metric coarse thread (e.g., M6×1.0, M8×1.25, M10×1.5, M12×1.75). They are fully compatible with standard metric hex nuts, coupling nuts, threaded inserts, and tapped holes following ISO 261/262. They are not compatible with UNC or UNF inch-thread hardware.

Can I use these for angled lifts, or vertical only?

Standard (non-shoulder) eye bolts like these are designed for vertical, in-line loading. For angled lifts, the working load must be significantly derated — typically to 50% at 45° and 25% at 90° from vertical. For frequent or critical angled lifting, a shoulder eye bolt or swivel hoist ring is generally the safer choice. Always follow applicable rigging standards for your region.

How do I convert the shank length from mm to inches?

Divide the millimeter value by 25.4 to get inches. Quick reference: 9mm ≈ 3/8", 12mm ≈ 1/2", 16mm ≈ 5/8", 20mm ≈ 3/4", 25mm ≈ 1", 30mm ≈ 1-3/16", 40mm ≈ 1-9/16", 50mm ≈ 2". Note that the shank length in the variant name refers to the threaded portion only — overall height including the eye ring will be greater.

How many pieces come in each order?

You select your pack quantity when choosing your variant: 1, 2, 3, 5, 10, or 20 pieces. Each piece is one complete eye bolt. Larger packs offer a lower per-unit cost, making them practical for stocking a workshop or completing a multi-point rigging installation.
