304 Stainless Steel Forged Eye Bolts — Reliable Anchor Points for Hanging, Rigging & Catenary Systems
Whether you're suspending a catenary wire across a patio, rigging a cable management system in a workshop, or anchoring a swing set in the backyard, a loose or corroded eye bolt is the last thing you want to discover mid-project. These 304 stainless steel forged eye bolts are built for DIYers, contractors, and fabricators who need a dependable anchor point that won't let them down — indoors or out.
Each eye bolt features a fully closed, forged ring head for maximum strength at the eye, with a metric threaded shank available in M5, M6, and M8 diameters. Lengths range from 20mm (≈0.79") to 150mm (≈5.91"), with both Full Thread and Thread Length 40mm options. Order in packs of 1, 3, 5, 10, 20, 30, 50, or 100 pieces to match your project scale — from a single repair to a full installation run.
Typical applications include catenary wire hanging systems for outdoor string lights, pendant lamp suspension in commercial interiors, cable tray anchoring in electrical installations, and load-bearing rigging points in woodworking or metalworking shops. The metric thread profile makes these forged eye bolts compatible with standard M5, M6, and M8 hardware across a wide range of DIY and professional projects.
🔩
Thread Compatibility: Standard metric coarse thread — M5, M6, M8 (ISO 261 / DIN 580 profile). Fits standard metric nuts, threaded inserts, and pre-tapped holes of the corresponding size.
✅ Key Features of These 304 Stainless Steel Forged Eye Bolts
-
🔗
Forged Closed Eye — The ring is forged as a single continuous piece, eliminating the weak point of a welded or bent-open eye and providing a secure loop for carabiners, shackles, and wire rope clips.
-
🛡️
304 Stainless Steel Construction — Resists rust, oxidation, and surface staining in outdoor, humid, and mildly corrosive environments — a step up from zinc-plated carbon steel alternatives.
-
📐
Wide Size Range — M5, M6, and M8 thread diameters with lengths from 20mm to 150mm cover the majority of catenary hanging, rigging, and structural anchoring applications in one product listing.
-
🔄
Full Thread & Partial Thread Options — Choose Full Thread for maximum engagement in shorter bolts or blind holes; choose Thread Length 40mm for longer bolts passing through clearance holes where only the tip needs to thread.
-
📦
Flexible Pack Quantities — Available in packs of 1 to 100 pieces, so you can grab a single bolt for a quick fix or stock up in bulk for a full catenary wire installation or contractor job.
-
⚙️
Metric Standard Thread Profile — Machined to ISO metric coarse thread tolerances, ensuring smooth engagement with standard M5, M6, and M8 nuts, threaded rods, and pre-tapped anchor points without cross-threading risk.

⚠️
Installation Note: For load-bearing applications, always install eye bolts with the eye oriented perpendicular to the direction of pull. Use a backing nut or locking nut where vibration is present. Consult a structural engineer for critical overhead or safety-critical rigging.
❓ Frequently Asked Questions
How do I choose the right length for my eye bolt?
The bolt length should be at least 1.5× the thickness of the material you're threading into. For example, if your beam is 30mm (≈1.18") thick, choose at least a 45mm bolt. Always add a few millimeters of margin so the threads engage fully. For through-bolt applications, match the bolt length to the material thickness plus washer and nut clearance.
What load can these eye bolts handle?
Working load limits vary by size and installation method. Generally, M5 eye bolts are rated for lighter loads (typically up to 50–80 kg vertical), M6 for medium loads (typically 80–150 kg), and M8 for heavier applications (typically 150–300 kg). Always apply a safety factor of at least 4:1 and consult an engineer for critical load-bearing installations.
Are these eye bolts suitable for outdoor or marine use?
Yes. These are made from 304 stainless steel, which offers good corrosion resistance in most outdoor environments including rain, humidity, and mild coastal conditions. For heavy marine or saltwater immersion applications, 316 stainless steel is generally recommended for superior chloride resistance.
What thread standard do these eye bolts use?
These eye bolts use standard metric coarse threads (M5, M6, M8) conforming to ISO 261 / DIN 580 thread profiles. They are compatible with standard metric nuts, threaded inserts, and pre-tapped holes of the corresponding size.
What is the difference between Full Thread and Thread Length 40mm?
Full Thread means the threaded shank runs the entire length of the bolt — ideal for shorter bolts or applications where maximum thread engagement is needed. Thread Length 40mm means only the bottom 40mm (≈1.57") of the shank is threaded, with a smooth shank above — commonly used for longer bolts where the smooth section passes through a clearance hole.
Can I use these for catenary wire or cable hanging systems?
Yes. Forged eye bolts are a standard hardware choice for catenary wire systems, pendant lighting, and cable management. The closed forged eye provides a secure anchor point for carabiners, shackles, or wire rope clips. Ensure the eye bolt is installed perpendicular to the load direction for maximum strength.
How many pieces come in each order?
You can choose your pack quantity when selecting a variant: 1, 3, 5, 10, 20, 30, 50, or 100 pieces. Larger packs offer a lower per-piece cost, making them ideal for contractors, fabricators, or bulk project needs.
