Sometimes you need a screw hook to hang a plant. Other times you need a screw eye to run a wire or chain through. Instead of buying two separate kits, grab a set that gives you both ā in rustproof 304 stainless steel. These screw hooks and screw eyes come in metric sizes from M4 up to M12, with both large and small loop options. The cup-style base (the curved "cup" just under the hook or eye) helps the fastener sit flush against wood or drywall for a clean, professional look. Whether you're hanging lightweight decorations in a bathroom (hello, humidity), securing cables in a workshop, or setting up a ceiling-mounted plant hanger, the 304 stainless construction means no orange rust spots down the road. Just drill a pilot hole and twist them in by hand or with pliers.
š© Why Choose These 304 Stainless Steel Screw Hooks & Eyes
Genuine 304 stainless steel ā Maximum corrosion resistance compared to plated steel or zinc hooks. Perfect for kitchens, bathrooms, outdoor covered areas, and coastal environments. No flaking, no rust stains.
Two styles in one system ā Screw hooks (curved open loop) for hanging items directly; screw eyes (closed ring) for threading ropes, chains, or using with carabiners. Choose what fits your project.
Metric sizes M4, M5, M6, M8, M10, M12 ā From tiny #4 (M4) for light craft projects up to M12 for heavy-duty hanging. Cup style provides a finished look and prevents the hook from sinking too deep.
Large & small loop options ā Small loops are discreet for picture hanging; large loops accommodate thicker rope, S-hooks, or multiple cables.
Ideal for wall and ceiling screw connections ā Use in wood studs, drywall with anchors, or directly into solid timber. Great for hanging plants, lightweight tools, bird feeders, wind chimes, string lights, and even as anchor points for storage nets.

ā Frequently Asked Questions
Q: Can I use these screw hooks and eyes outdoors in the rain?
A: Yes. 304 stainless steel is highly resistant to moisture and mild salt exposure. These will not rust like zinc-plated hooks. For direct rain or sprinklers, they'll hold up fine. For constant saltwater spray (beachfront), 316 stainless is better, but 304 is still a solid upgrade over carbon steel.
Q: Do I need to pre-drill before installing these into wood?
A: Highly recommended. For softwoods (pine, cedar), drill a pilot hole about 1/16" smaller than the screw's diameter. For hardwoods (oak, maple), drill a pilot hole that matches the root diameter (the solid core between threads). Pre-drilling prevents splitting, especially with larger M8, M10, and M12 sizes. For M4 and M5 in softwood, you can often screw them in by hand without pre-drilling.
Q: What's the difference between a cup hook and a regular screw hook?
A: A cup hook has a small curved "cup" or shoulder just below the hook loop. This cup sits flush against the surface when the hook is fully screwed in, giving a finished look and preventing the hook from sinking too deep. It also adds a bit of extra strength. These are cup-style screw hooks and eyes ā the cup is part of the design.
Q: How much weight can each size hold?
A: Load capacity depends on wood type, pilot hole accuracy, and insertion depth. As a rough guide for solid wood: M4/M5: 5-8 lbs; M6: 10-15 lbs; M8: 20-25 lbs; M10: 30-40 lbs; M12: 50+ lbs. Always test with your specific application. For ceiling installations, use screws long enough to penetrate at least 1" into a stud. Never hang from drywall alone without proper anchors.
Q: Can I get these in a single size pack instead of mixed?
A: Yes, we offer individual sizes and quantities. If you need, for example, 20 pieces of M6 screw hooks only, please contact us. We can customize orders. The listing shows the full range, but you're welcome to request a specific size and style. Just send a message with your requirements.
