PATIKIL Double Ended Swivel Hook (M6) Review: small stainless workhorses for swings, chains and DIY rigs

I grabbed this 5-pack of PATIKIL M6 double ended swivels because I was tired of cheap zinc hooks starting to rust after one season in the garden. I needed something for a kids’ tree swing, a hanging chair on the balcony, and a couple of chain connections in the shed. On paper, 304 stainless steel and a 240 kg rating sounded solid, especially for the price.

After getting them in hand, my first reaction was basically: “Alright, these are not toy hardware.” Each piece has some weight to it, the threading on the jaw side feels decent, and the swivel moves smoothly out of the box. No weird grinding or sloppy play, which is what you often get with budget swivels. They’re compact, but not flimsy.

I’ve been using them for a few weeks in mixed conditions: one permanently outside on a tree swing, one under a covered terrace with a hammock chair, and another indoors to join two chains on a heavy punch bag. So they’ve seen rain, some light wind stress, a bit of kid abuse, and regular rotation from the hammock. That’s enough to see if they’re junk or if they hold up.

Overall, I’d say these hooks do what they’re supposed to do: they swivel, they don’t rust overnight, and they haven’t bent or deformed on me. They’re not perfect and they’re not magic – you still need to know what you’re doing with load and installation – but for small to medium jobs around the house and garden, they’re pretty solid. Just don’t treat that 240 kg rating like a license to hang a car off one of them.

For what you get – five stainless steel M6 swivels – the value is pretty solid. Buying similar hardware individually at a local DIY store usually costs more per piece, and half the time it’s not even stainless, just chrome-plated mild steel. Here you get a full set that should cover several projects: swings, hammock, punching bag, maybe a couple left for camping or a hanging planter setup.

What I like is that they sit in a nice middle zone: not bargain-bin trash, but also not overpriced “marine-grade” stuff that costs a fortune. For home and garden projects, they hit a good balance between cost and quality. If you compare them to premium 316 stainless swivels, those would definitely handle harsher environments better, but they’re usually priced higher and overkill for a simple backyard swing.

On the downside, the compact size and lack of locking features do limit their use. If you need bigger openings, or if you’re doing something safety-critical (like serious climbing or pro rigging), you’d be better off with specialized gear, even if it costs more. In that sense, these are good value only if your expectations match what they’re built for: light to medium static or semi-dynamic loads around the house.

For my own use – kids swing, hammock, punch bag, and a spare or two for future projects – I’m happy with what I paid. They’re not the cheapest option you’ll find online, but considering the material, finish, and the fact that all five pieces were usable with no defects, I’d say the price is fair. If you need exactly this type of small stainless swivel in quantity, the pack is a sensible buy.

The design is pretty straightforward: eye on one end, jaw with a removable pin on the other. That combo actually makes these more flexible than simple double-eye swivels. I used the eye side to connect to fixed points (like a ceiling hook or chain), and the jaw side to clamp onto loops or rings that I didn’t want to re-knot or re-thread. The pin unscrews fully, slides out easily, and there’s enough clearance to grab it with fingers, even if your hands aren’t tiny.

The 360° swivel actually works as advertised. On the tree swing, the seat can spin without winding the rope into a mess. Same for the hammock chair: it turns smoothly when you twist your body, and the swivel keeps the chain from twisting up. There’s a bit of resistance, but that’s normal – if it spun super loosely, I’d worry about sloppy tolerances. Here it feels controlled but free enough that you don’t notice it in use.

Where the design shows its limits is the jaw opening and ring sizes. The lower inner size (13 x 12 mm) is fine for small to medium hardware, but if you’re trying to attach thicker eye bolts, big wooden swing hooks, or chunky rope knots, you’ll be fighting for space. I had to ditch one planned setup because the jaw simply wouldn’t pass around a thicker welded ring. So these are better for slimmer chains, carabiners, and standard swing hardware rather than oversized fittings.

Another small point: there’s no safety wire or locking feature on the pin. For normal home use, screwing it in tight is enough, but if you’re paranoid or planning something more critical, you might want to add a dab of thread locker or check them regularly. Design-wise, they’re simple, practical, and mostly well thought out, but they’re clearly aimed at light to medium duty, not professional rigging or climbing.

The hooks are made from 304 stainless steel, which is kind of the standard mid-level stainless. It’s not the toughest thing on earth, but for garden, marine-ish, and general outdoor use, it’s usually good enough. I’ve had them outside for a few weeks now – one fully exposed on a tree, another partly covered on a terrace – and so far there’s no visible rust, no discoloration, and no weird stains. They still look like the day I unboxed them, just a bit dusty.

The surface finish is a basic smooth steel look, not mirror-polished, but also not rough. You can run your fingers over all the edges without cutting yourself. I checked the weld areas and bends: nothing obviously weak, no hairline cracks, and the metal thickness (about 5.9 mm wire diameter) gives a decent sense of security. These don’t feel like those flimsy chrome-plated hooks that bend if you look at them sideways.

That said, 304 stainless is not magic in salty or very harsh environments. If you’re planning to leave these on a boat in constant sea spray or in a super corrosive industrial setting, I’d keep an eye on them or go for 316 stainless instead. For a normal garden, balcony, garage, or occasional camping, 304 is perfectly fine and much better than cheap galvanized hardware that starts to flake after one season.

In terms of consistency, all five pieces look like they came from the same batch and process. No odd color differences, no half-finished threads, and the pins are straight and fit their holes without wobble. For the price bracket, the material quality is better than I expected. Not premium, but clearly above the usual bargain-bin stuff you find in random hardware assortments.

Durability-wise, I’ve put them through a basic real-life test: constant outdoor exposure, regular use, and a bit of abuse from kids. After a few weeks on the tree swing, the swivel still turns, the pin hasn’t walked itself loose, and the surface only shows some dirt, no rust spots. Same for the hammock setup – it gets used several evenings a week, and the swivel hasn’t loosened up or developed any strange play.

I also tried a simple “trust check”: I hung from one with my own weight (around 80 kg) in a static setup, just off a low anchor so I wouldn’t break my neck if something failed. No ping, no bending, no feeling that the metal was about to give. I wouldn’t call that scientific testing, but it does give some confidence that they can handle typical human loads with a decent margin, as long as you don’t do anything stupid.

Where durability might be a question mark is very long-term outdoor use – like several years in rain, snow, UV, maybe near the sea. 304 stainless should hold up reasonably well, but I’d still follow what the brand hints at: check them now and then for deformation or cracks. The swivel joint is the weak spot on any such piece of hardware. So far mine are fine, no looseness or obvious wear, but I haven’t had them for a full season yet.

Overall, they give a decent feeling of reliability for household projects and garden setups. They’re not industrial-grade rigging gear, but they’re also not cheap throwaways. If you install them correctly and don’t overload them, I’d expect them to last several seasons easily. If you’re planning something permanent and critical, I’d still budget for periodic inspection or step up to a more heavy-duty model.

In the box you get 5 identical M6 double ended swivel hooks and a tiny user manual that’s basically a safety note. No fancy packaging, just a simple bag. Honestly, that’s fine for this kind of hardware – I’d rather they put money into the metal than into cardboard. Each swivel is about 67 mm long, so roughly two and a half fingers in length, and has one eye side and one jaw (with a threaded pin) on the other.

The listed load capacity is 240 kg / 529 lbs. Important detail: that’s a theoretical working load, not “go hang 240 kg dynamically on this and swing like crazy”. For my use, I stayed way below that – kids swing maybe 30 kg max, hammock about 90 kg with some movement, and the punch bag around 40–50 kg. No issues so far. The inner ring sizes are small but usable: 18 x 16 mm on the upper ring and 13 x 12 mm on the lower. It’s enough for standard carabiners, small shackles, chains, or decent-thickness rope with a knot or loop.

Out of the five, all looked consistent. No obvious machining defects, no sharp burrs, and the pins all screwed in and out without needing pliers. The swivels rotate freely by hand. There is a tiny bit of lateral play if you really wiggle them, but nothing that feels unsafe. For a budget brand, the overall presentation is “simple but functional”, which is exactly what I want for this sort of part.

If you expect a detailed spec sheet with engineering-style testing, you won’t find that here. You get basic dimensions, the material (304 stainless), origin (China), and that’s it. So you still need to use your brain, especially if you plan to use these for anything where a failure could seriously hurt someone. For home and garden stuff, the info given is enough to know what you’re buying and where it fits.

In practice, the main job of these swivels is simple: stop ropes and chains from twisting and handle moderate loads without bending. On that front, they do the job. On the kids’ tree swing, the rope used to twist on itself and jam the seat sideways. After adding one of these between the rope and the overhead hook, the swing now rotates freely and the rope no longer winds up like a spring. Same story with the hammock chair – it can spin without you feeling like the whole chain is tightening above your head.

I also used one on a heavy punch bag. Before, the chain would slowly twist, and every few days I had to untangle it. With the swivel in place, the bag can spin when I hit it off center, and the chain stays relaxed. There’s some minor creaking noise sometimes, but that’s more the chain than the swivel. The swivel itself has stayed smooth, with no grinding or catching under movement.

Regarding load, I didn’t go anywhere near the claimed 240 kg limit, and honestly I wouldn’t want to test that at home. But with roughly 90 kg in the hammock and active movement, there’s been no bending, no deformation, and no visible stress marks. I checked the jaw gap and the pin alignment after a few sessions, and everything still looks straight. For typical home uses – swings, hammocks, bags, hanging planters – it feels well within its comfort zone.

The only catch is that the small size limits some use cases. If you want to connect really thick ropes or oversized eye bolts, you might find yourself stuck. Also, there’s no built-in safety mechanism, so you’re relying on your own installation. If you’re lazy about checking tightness or you overload them, that’s on you. As long as you stay within sensible limits and use them as intended, they’re effective and pretty hassle-free.
