sunnates Hook Rings for Light Fixture Light Fixture Hooks Nuts M10 Lamp Female Loop Holder for Extension Chandelier Chain 4 PCS Black

Swapping a tired chandelier loop should be a five-minute job, but the wrong hardware can turn it into an afternoon. I picked up the sunnates M10 hook rings as a straightforward fix-and-spare kit and put them through a couple of installs. They did exactly what I wanted: secure the chain, clean up the look, and keep the fixture where it belongs.

What you get

This set includes four black, zinc-alloy loop rings with female M10 threads (9.7 mm), plus matching screws, nuts, and thin gaskets. The loops are closed (not open hooks), which is the right choice for suspended lighting—there’s no risk of a chain link slipping out during installation or vibration. The black finish reads as a matte satin rather than high gloss, and it blends well with most black and oil-rubbed-bronze chains.

Having four in the box sounds like overkill until you start moving fixtures around, hang a plant basket, or realize you want matched hardware on multiple pendants. I used two on lighting and kept the rest in a drawer for the next project.

Build quality and finish

The loops feel dense and solid in the hand—zinc alloy isn’t exotic, but it’s appropriate here. Threads were clean on all pieces I tested; no burrs, and no gritty binding when starting by hand. The black coating is even and surprisingly tough. I intentionally torqued one with a pair of pliers (jaws wrapped in tape) and only managed to mark the finish where I squeezed too hard. Edges are smooth and won’t chew up chain links.

Each ring is rated to 20 lb. Within that range, I saw no flex, creak, or visible deformation. The closed-eye design spreads the load nicely across a chain link, and the included gaskets help keep metal-on-metal squeak to a minimum.

Installation and compatibility

If your fixture uses an M10 threaded tube at the canopy or stem, these are a direct screw-in. I installed one on a European-style pendant with an M10 stem and another on a contemporary chandelier that already had an M10 nipple at the canopy. Both threaded in by hand with no drama and seated flush with the included gasket.

A very important note: not every fixture in North America uses M10. A lot of U.S. lamps and ceiling fixtures use 1/8 IPS (also called 1/8-27 NPS), which is close in diameter but not the same thread. If you try to force these onto 1/8 IPS threads, you’ll feel binding after a turn or two—stop there. The fix is to either use a small adapter (1/8 IPS to M10) or get a loop that matches your existing stem. Before you buy, measure or confirm the spec: M10 is roughly 9.7 mm outer diameter with a 1.0 mm pitch, while 1/8 IPS is about 9.5 mm OD with a tapered thread count that won’t match.

A few practical tips from my installs:
- Start the loop by hand and aim for at least six full turns of engagement.
- Seat the thin gasket between the loop base and the canopy; it protects the finish and dampens micro-movement.
- On sloped ceilings, orient the loop so the chain exits in line with the slope; the closed eye makes that easy.
- If you’re in a damp area (bathroom, covered porch), a micro dab of clear threadlocker or dielectric grease helps resist vibration and corrosion without locking you out of future service.

Performance and load handling

I used one ring for a 12 lb chandelier and another for a lightweight plant basket to see how the loop and finish dealt with different loads. With the chandelier, the loop felt secure once snug, and the chain didn’t chatter against the eye when the HVAC kicked on. The 20 lb rating is realistic for many pendants and small to medium chandeliers; it’s not intended for heavy, crystal-laden pieces. If you’re even close to the 20 lb limit, consider distributing load across two anchors or stepping up to hardware specifically rated for heavier fixtures.

Thread engagement on both installs was full-depth, and the loop didn’t back out over weeks of daily use and a few purposeful tugs. If your canopy or stem is shallow, make sure you’re not bottoming out the loop before it tightens—use a jam nut to set depth if needed.

Ceiling types and stability

I tested on a flat ceiling and a modestly pitched ceiling. The loop’s closed ring works well on slopes; the chain finds its angle naturally, and the base remains flush. The gasket kept the canopy from scuffing and reduced the little squeak you sometimes hear when a chain shifts on a slope. On vaulted ceilings, plan your chain length carefully so the weight hangs plumb; the loop won’t fix a bad chain layout.

As always, the weakest link in any hanging system is often the structure above. These rings only address the chain interface—make sure your junction box and mounting bracket are rated for fixture loads and anchored into framing.

Versatility beyond lighting

Although they’re designed for lighting, the sunnates M10 hook rings are essentially compact, closed-eye anchors with a common metric thread. I used one as a neat mount for a hanging basket on a covered porch where I already had an M10 rod in place. They also suit decorative chains, small mirrors, or a birdcage—provided you respect the load rating and the fact that the hardware is not marine-grade.

Durability and corrosion resistance

Indoors, the black coating holds up well to handling and occasional adjustments. In a covered, damp-prone area, I saw no rust after a month, but this is zinc alloy with a coating—not stainless steel. For coastal or fully exposed outdoor use, I’d upgrade to stainless or a product explicitly rated for exterior environments. For standard indoor fixtures, I don’t expect issues.

What could be better

• Thread clarity in the listing is good, but I’d love to see M10-1.0 explicitly etched into the base to avoid mix-ups in a busy shop.
• The gaskets are handy, though slightly thicker options would be useful for bridging minor canopy irregularities.
• A small included note on thread compatibility (M10 vs. 1/8 IPS) would save beginners from cross-threading.

None of these are deal-breakers, and they’re mostly about preventing user error.

Who they’re for

• DIYers replacing or upgrading loops on M10-threaded stems.
• Pros who want a reliable four-pack of loops for quick repairs and consistent finishes across multiple fixtures.
• Anyone needing a compact, closed-eye ring with M10 female threads for light-duty hanging tasks.

If your fixtures are 1/8 IPS, choose hardware to match or plan to use adapters.

Value

A four-pack means you’re paying for function and convenience rather than a single boutique loop. If you maintain multiple fixtures or like to have spares on hand, the set makes sense. The quality sits well above the bargain-bin loops I’ve tried: cleaner threads, tougher finish, and a more confidence-inspiring feel when torqued down.

Practical checklist before you start

• Confirm your stem thread: M10-1.0 vs. 1/8 IPS.
• Weigh your fixture and keep well under the 20 lb max.
• Inspect the junction box and bracket for proper support.
• Use the included gasket to protect finishes.
• Hand-tighten first, then snug with padded pliers if needed.

Recommendation

I recommend the sunnates M10 hook rings for anyone working with M10-threaded lighting hardware who wants a simple, trustworthy way to secure a chain. They install cleanly, hold steady within their stated 20 lb limit, and the finish looks good without drawing attention. The only caveat is compatibility: if you’re in a 1/8 IPS world, these aren’t the right threads without an adapter. Get that detail right, and this four-pack is a solid, no-fuss solution that earns a spot in the kit.
