Zinc Plated Screw Eye Hooks — Heavy Duty Hanging Hardware for Wood, Garden, Shed & Marine Use
Finding a screw eye hook or screw-in hook that actually holds up outdoors — without rusting out after one season or stripping when you try to drive it — is a recurring frustration for homeowners, contractors, and boaters alike. Whether you're rigging a garden shed, hanging plant baskets from a pergola, routing cable along a fence, or fitting out a boat with fender hooks, you need hardware that installs cleanly and stays put through weather and load cycles.
This listing offers heavy duty zinc plated steel screw eye hooks and screw-in hooks in two head types — Screw In Hooks (open hook head) and In Eye Hooks (closed loop/eye head) — across a wide size range. Screw In Hooks are available from 16mm (≈5/8") in size #1 up to 105.2mm (≈4-1/8") in size #16. In Eye Hooks range from 13.6mm (≈17/32") in size #0 up to 51.78mm (≈2") in size #14. Packs are available in 10 or 50 pieces, making this listing suitable for both single-project use and bulk restocking.
Typical applications include hanging string lights and lanterns from deck beams or pergola rafters using screw-in hooks, routing guide wire and cable through closed eye hooks along shed walls or fence lines, fitting boat fender hangers and rigging points on wooden marine structures, and organizing tool hooks and hanging storage in garages and workshops. The zinc plating provides corrosion resistance for general outdoor and sheltered marine environments.
🔩 Compatibility Note: These hooks are designed for installation into wood substrates with a pilot hole. For use in metal, a pre-drilled and tapped hole is typically required — contact us to confirm suitability before ordering.
⚠️ Size Guide: Sizes are listed in both mm and traditional US hardware gauge numbers (#0–#16). Screw In Hooks and In Eye Hooks use different size scales — check the variant options carefully. If unsure which size fits your project, refer to the FAQ below or contact us.
✅ Key Features of These Zinc Plated Screw Eye Hooks
🛡️ Zinc Plated Steel Construction — The zinc coating provides a protective barrier against rust and corrosion, making these hooks suitable for outdoor garden, shed, and sheltered marine environments where bare steel would degrade quickly.
🔄 Two Head Types in One Listing — Choose open Screw In Hooks for quick-attach hanging tasks (plant baskets, tool hangers, fender lines) or closed In Eye Hooks for threading wire, rope, or cable through permanently — no need to place two separate orders.
📏 Wide Size Range #0 to #16 — Covering 13.6mm (≈17/32") through 105.2mm (≈4-1/8"), this range spans from delicate picture-hanging wire guides up to heavy duty boat rigging hooks and structural shed hardware.
📦 10-Pack or 50-Pack Options — Buy exactly what your project needs with a 10-piece pack, or save per-unit cost with a 50-piece bulk pack — ideal for contractors, large installations, or keeping a workshop supply stocked.
🔧 Screw-In Installation into Wood — The threaded shank drives directly into wood with a pilot hole, providing a secure mechanical hold without adhesives or additional hardware. Suitable for softwood and hardwood framing, shed cladding, and timber decking.
⚓ Versatile Indoor & Outdoor Applications — From hanging garden shed tools and routing fence cable to fitting marine fender hooks and organizing garage storage, these hooks cover a broad range of DIY and light commercial hanging hardware needs.

❓ Frequently Asked Questions
How do I choose the right size screw eye hook for my project?
Match the size number to your load and the material you're fastening into. Smaller sizes (#0–#3, approximately 13–24mm / ½"–1") are generally suited for lightweight tasks like hanging picture wire, small decorative items, or routing thin cable. Mid-range sizes (#4–#8, approximately 28–56mm / 1"–2¼") handle medium loads such as plant hangers, shed cable guides, and tool hooks. Larger sizes (#10–#16, approximately 63–105mm / 2½"–4") are typically used for heavier structural applications like boat rigging, gate hardware, or heavy garden fixtures. When in doubt, size up for a more secure hold.
What load weight can these hooks support?
Load capacity depends on the size, installation depth, and substrate material. Smaller sizes (#0–#3) are generally suited for light-duty hanging tasks. Larger sizes (#10–#16) can typically handle heavier loads when fully embedded in solid structural timber. Always account for dynamic loads — swinging, wind, or vibration — which can be significantly higher than static weight. For critical load-bearing applications, verify the specific load rating or contact us before ordering.
Are these suitable for outdoor, marine, or wet environments?
Yes, for general outdoor use. The zinc plating provides a protective layer against rust and corrosion, making these hooks well-suited for garden sheds, fences, pergolas, and sheltered marine applications such as wooden boat fittings and dock hardware. For prolonged direct saltwater spray or highly aggressive coastal environments, additional protective coating or stainless steel alternatives are generally recommended for longer service life.
What is the difference between Screw In Hooks and In Eye Hooks — which should I choose?
Screw In Hooks (open hook) — Best when you need to attach and detach items quickly without threading. Common uses: hanging plant baskets, tool hooks in a garage or workshop, boat fender lines, curtain cable systems, and garden shed organizers.
In Eye Hooks (closed loop) — Best when you need to thread wire, rope, or cable through the fastener and keep it permanently secured. Common uses: picture hanging wire guides, cable routing along fences or shed walls, rigging points, and string light anchor points.
Can these hooks be installed in metal as well as wood?
These hooks are designed primarily for installation into wood substrates. For use in metal, a pre-drilled and tapped hole matching the shank thread would typically be required. Contact us to confirm suitability for your specific metal application before ordering to ensure a proper fit.
Do I need to pre-drill a pilot hole before installing?
Yes, a pilot hole is strongly recommended in all cases. Use a drill bit slightly smaller than the shank diameter. For larger sizes (#6 and above) and in hardwoods, a pilot hole is essential to prevent wood splitting and to make installation manageable. For smaller sizes (#0–#3) in softwoods, you may be able to install without one, but a pilot hole still gives a cleaner, more accurate result and reduces the risk of the wood cracking.
Should I buy the 10-pack or the 50-pack?
The 10-pack is ideal for single projects or when you need just a few hooks — hanging a set of lights, a plant basket, or a small cable run. The 50-pack offers a lower per-unit cost and is well-suited for contractors, larger installations (fencing, shed fit-outs, boat rigging), or anyone who wants to keep a supply on hand for ongoing DIY and home improvement projects.
