Galvanized O-Ring Eye Bolts M6–M20 — Reliable Lifting & Rigging Hardware for Every Job

Whether you're rigging a load on a job site, hanging equipment in a workshop, or securing gear outdoors, finding a galvanized lifting eye bolt that fits your exact thread size and length shouldn't be a hassle. DIYers, contractors, and riggers alike need hardware that threads in cleanly, holds firm under load, and resists rust without constant maintenance — and that's exactly what these O-ring eye bolts are built for.

Each bolt features a fully closed O-ring loop head and a metric-threaded shank, available in thread diameters from M6 (≈1/4") through M20 (≈3/4"), with shank lengths ranging from 12mm (≈1/2") to 60mm (≈2-3/8"). The zinc galvanized finish provides a protective barrier against corrosion. Order in packs of 1, 2, 3, 5, 8, 10, 15, 20, 30, or 50 pieces to match your project scale.

These metric eye bolts are well-suited for overhead rigging and load-securing in construction and manufacturing, hanging pulleys, cables, or rope systems in garages and workshops, and outdoor tie-down or anchor point applications where weather resistance matters. Long-tail use cases include galvanized eye bolt for wood beam installation, M10 lifting eye bolt for machinery, and M12 O-ring bolt for cable management.

🔩 Thread Compatibility: ISO metric coarse thread (M6–M20) — fits standard metric nuts, tapped holes, and threaded inserts per DIN/ISO specifications.

✅ Key Features of These Galvanized O-Ring Eye Bolts

  • 🔗 Closed O-Ring Loop Design — The fully enclosed ring head eliminates the risk of rope or hook slipping out during vertical lifts, making it more secure than open-hook alternatives for overhead rigging applications.
  • 🛡️ Zinc Galvanized Corrosion Resistance — The galvanized coating shields the steel from rust and oxidation, extending service life in outdoor, humid, or mildly corrosive environments compared to bare steel fasteners.
  • 📐 Wide Metric Size Range (M6–M20) — With thread diameters spanning M6 through M20 and multiple shank lengths per size, you can find the exact metric lifting eye bolt to match your tapped hole or nut without adapters or modifications.
  • 📦 Flexible Pack Quantities — Choose from single pieces up to 50-packs, so you can grab exactly what you need for a one-off repair or stock up for ongoing rigging and construction work without over-ordering.
  • ⚙️ Standard ISO Metric Thread Profile — Machined to ISO metric coarse thread standards, these eye bolts thread smoothly into compatible nuts and tapped holes without cross-threading, reducing installation time on the job.
  • 🏗️ Versatile Rigging & Anchor Point Use — Suitable for attaching lifting slings, chains, ropes, or cables in workshop hoists, load-securing rigs, and structural anchor point installations across a range of thread sizes.

❓ Frequently Asked Questions

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

Match the thread diameter to your tapped hole or nut size. For shank length, the threaded portion should typically engage at least 1.5× the bolt diameter in depth — for example, an M8 bolt generally needs at least 12mm of thread engagement for a secure hold. Quick inch conversions: 12mm ≈ 1/2", 16mm ≈ 5/8", 20mm ≈ 3/4", 25mm ≈ 1", 30mm ≈ 1-3/16", 50mm ≈ 2".

What is the working load limit of these eye bolts?

Working load limits vary by thread size and installation depth. As a general guideline, smaller sizes like M6 are typically rated for lighter loads (around 50–100 kg), while larger sizes like M20 can generally handle significantly heavier loads. Always apply a safety factor — typically 4:1 or higher — for overhead lifting, and consult a certified load chart for your specific size and application.

Are these eye bolts suitable for outdoor or marine environments?

Yes. The galvanized zinc coating provides solid corrosion resistance for outdoor use in rain, humidity, and mild weather exposure. For prolonged saltwater or marine environments, additional protective coatings or stainless steel alternatives are generally recommended for long-term performance.

What thread standard do these eye bolts use — are they compatible with standard metric hardware?

These eye bolts use standard ISO metric coarse threads (M6 through M20), compatible with standard metric nuts, washers, and tapped holes following DIN/ISO specifications. They are not compatible with UNC/UNF inch-standard threads — please confirm you need metric before ordering.

Can I use these eye bolts for angled or side loads?

O-ring eye bolts are generally designed and rated for straight vertical (axial) lifts. For angled loads, the working load limit is typically reduced significantly — in some cases by 50% or more at 45°. If your application consistently involves side or angular loading, a swivel hoist ring is generally the safer choice.

How many pieces come in each pack, and which quantities are available?

Pack quantity options vary by size and include 1, 2, 3, 5, 8, 10, 15, 20, 30, and 50 pieces. Select your thread size and length first, then choose your preferred quantity. Larger packs offer better per-unit value for bulk projects or ongoing maintenance needs.

Do I need a nut or washer with these eye bolts?

In most installations, a matching metric nut and flat washer are recommended to distribute the load across the surface and prevent pull-through. These are not included with the eye bolts and should be sourced separately in the matching metric size (e.g., M8 nut for an M8 eye bolt).
