Galvanised Eye Screws & Stainless Eye Bolts — Metric Closed-Loop Threaded Rings for DIY, Rigging & Enclosure Builds
When a standard screw won't do the job, DIYers, makers, and light-rigging enthusiasts reach for a reliable eye screw. Whether you're routing cables through a panel, hanging a load from a timber joist, or securing a lashing point on a project enclosure, a loose or corroded eye bolt is the last thing you want mid-build.
These galvanised eye screws and stainless eye bolts feature a fully closed circular loop head on a metric-threaded shank. Available in Carbon Steel – Galvanised or Stainless Steel A2, with thread diameters from M3 to M12 (approximately 0.12 in to 0.47 in) and shank lengths from 8 mm to 100 mm (approximately 0.31 in to 3.94 in). Sold individually or in packs of 5 to suit single-fix and multi-point installations alike.
Typical applications include cable management and wire routing in PC builds and electronics enclosures, light suspension and hanging fixtures in workshop or retail settings, lashing and tie-down anchor points on DIY frames and carts, and securing guy-wires or tensioned lines on outdoor structures where a closed-loop threaded ring bolt is required.
🔩
Compatibility: Standard metric thread (M3–M12). Fits any metric-tapped hole or pre-drilled pilot hole of the corresponding diameter. Verify thread pitch against your application before ordering — see variant options for full size breakdown.
✅ Key Features of These Galvanised Eye Screws & Stainless Eye Bolts
🔒
Fully Closed Loop Head
The circular eye is fully closed — no gap — providing a secure anchor point for hooks, carabiners, wire rope, or cord without risk of accidental disengagement.
🛡️
Two Material Options
Carbon Steel – Galvanised offers a zinc-coated surface for general indoor and sheltered outdoor use. Stainless Steel A2 (304 grade) provides corrosion resistance for damp, humid, or light marine environments.
📐
Wide Metric Size Range
Thread diameters M3 through M12 and shank lengths from 8 mm to 100 mm cover the majority of DIY, maker, and light-rigging applications without needing multiple suppliers.
📦
Single or 5-Pack Quantities
Order one for a spot repair or a pack of 5 for multi-point installations — both options are available across the full size range so you only buy what you need.
⚙️
Standard Metric Thread
Coarse metric thread profile is compatible with standard tapped holes and metric nuts, making these eye screws straightforward to install with no specialist tooling required.
🔧
Round Head Style
The round eye head sits flush against the mounting surface when fully driven, distributing load evenly and reducing stress concentration at the entry point.

❓ Frequently Asked Questions
Which size eye screw should I choose for my application?
Match the thread diameter to your tapped hole or the pilot hole you plan to drill. As a general guide: M3–M4 suit lightweight cable routing and small panel fixings; M5–M6 work well for medium-duty hanging and lashing points; M8–M12 are appropriate for heavier structural anchor points. Always verify the shank length leaves adequate thread engagement — typically at least 1× the thread diameter in depth for timber, and 1.5× for metal.
What is the difference between the Galvanised and Stainless Steel A2 options?
Carbon Steel – Galvanised eye screws have a zinc coating applied to the steel surface, which provides corrosion resistance in dry indoor and sheltered outdoor conditions. Stainless Steel A2 (304 grade) contains chromium and nickel, giving it inherent corrosion resistance suitable for damp, humid, or light marine environments without a surface coating that can chip or wear. For long-term outdoor or wet-area use, A2 stainless is the more durable choice.
Are these eye screws suitable for load-bearing or overhead lifting?
These eye screws are designed for light-duty anchoring, cable routing, lashing, and hanging applications typical in DIY and maker projects. They are not rated or certified for overhead lifting or safety-critical load-bearing use. For lifting applications, always use certified lifting eye bolts with a marked Working Load Limit (WLL) and comply with applicable safety standards.
Can I use these in outdoor or marine environments?
The Galvanised variants are suitable for sheltered outdoor use where they are not continuously exposed to moisture or salt spray. For outdoor installations with regular rain exposure or coastal/marine environments, the Stainless Steel A2 option is recommended. A2 stainless resists rust in most atmospheric and mildly corrosive conditions, though it is not rated for full immersion in seawater (which typically requires A4/316 grade).
What pilot hole size should I drill before installing an eye screw into timber?
For timber installation, drill a pilot hole approximately 70–80% of the thread diameter to allow the thread to bite without splitting the wood. For example, an M4 eye screw (4 mm thread) would typically use a 3.0–3.2 mm pilot hole. For harder timbers, use the larger end of that range. Always drive the eye screw by hand or with a rod through the eye loop — do not use power tools at high torque, which can strip the thread or split the substrate.
Do these eye screws come with a nut or washer?
These eye screws are supplied as individual fasteners only — no nut or washer is included. If your installation requires a nut to secure the eye screw through a panel or plate (bolt-through configuration), you will need to source a matching metric nut separately. Standard metric coarse nuts in the corresponding size (M3–M12) are widely available and compatible with these eye screws.
How do I choose between ordering 1 piece or a pack of 5?
The single-piece option is ideal for spot repairs, prototyping, or installations where only one anchor point is needed. The 5-pack offers a lower per-unit cost and is suited to multi-point installations — such as routing a cable run with multiple tie-off points, or setting up a series of hanging fixtures. Both options are available across the full M3–M12 size range.
