Stainless Steel 316 Swivel Eye Snap Shackle - Marine Grade Quick Release Jaw Swivel Sailboat Shackles - Marine Boat Sailing Rigging - for SCBA Mask & Spinnaker Halyard - Pack of 2

These swivel snap shackles employ a mechanism that’s slightly different from carabineers. It basically requires an intentional pull on the pin before it can be detached, for quick connecting. It’s not going to be secure as a threaded shackle in ultimate load strength but is more vibration resistant. This shackle has a really smooth jaw mechanism and pin detent that’s also not weak. It’s going to be great for everyday attachments, and I’m glad I got this to use on my boat and yard ropes.

I grabbed these Snap Shackles the second I saw them without hesitation. I am glad I did as they are impressive for the price. Granted - sailing season for me is still a few months out and my boat is sitting in the yard with dirt and mold on it awaiting the spring cleaning (See picture) - but I look forward to using these this summer for certain. I may be a little nervous using these on a "sailing yacht" - but honestly anyone that sails those boats don't look for the budget shackles. But these will be perfectly overengineered for my O'Day Mariner 19.Until then - these type clips have so many uses other than around the boat. Today I used it as a component in my home gym as a quick release for my weight stack lever on my rack. Much better than the carabiner I have been using.

Inspection and testing of two 3.5" Faneta 316 stainless steel swivel snap shackles evidenced solid construction and a serviceable finish. However one of the plunger pins failed to return to lock position when I first retracted it. After manipulating the pin back and forth a few times the mechanism smoothed out enough to return to lock position driven by spring recoil alone. Testing with a magnet evidence slight magnetism among all components as would be expected with 316 stainless steel. Measurements matched those in the listing. The shackles weight about 5 ounces (140 grams).I'm giving these swivel snap shackles 4 stars, taking one off for the rough plunger pin, with value offered at the price in mind but I will offer a word of warning, keep the 800 lb working load limit in mind when employing them. Although these snap shackles may look similar they are not comparable to those which cost 8 times as much, or more. Among other qualities expensive marine brand name snap shackles are typically made from special martensitic stainless steels which have been forged rather than cast. They can offer twice the WLL, or more, and deform initially rather than failing suddenly.I use expensive brand name marine rigging fittings for critical applications because loads on sails can increase suddenly and enormously with building wind speed. Wind load increases as the cube of the increase in wind speed, hence doubling of the wind speed octuples the load, not the square as some believe and we were taught in high school physics -- KE = 1/2 mass times velocity squared (because the wind mass is not fixed). Hence key rigging fittings need to be able to handle much higher loads than one might expect, suddenly in heavy gusts, before failing. Failure of one fitting can lead to a domino effect across the rig causing serious damage and potentially endangering lives.To add context to this warning I'll recount an experience offshore. Many years ago I crewed on a beautifully constructed and, thankfully, very strong 54' Maple Leaf sailing offshore from Marina Del Rey to Cabo San Lucas and one night we were flying a big asymmetric spinnaker in building conditions. Another crew member and I suggested more than once that we get the spinnaker down but the owner had other ideas; we were flying through the water and he liked it (limited at hull speed, but it was exciting). Long story short we eventually heard a loud bang and the big boat immediately broached hard creating chaos below and above. Among other things a heavy old microwave oven went flying across the 15 foot beam (suddenly approaching vertical), luckily not hitting anyone but smashing into the nav station. The vessel broached hard again before we could release the spinnaker sheet and battle the raging sail back down on deck without adding spinnaker converted to sea anchor to our problems in the developing gale. We are lucky nobody went overboard because that is the last we would have seen of them (only bruises and cuts were suffered). We later discovered the owner had used an inadequate fitting for a critical function and it had failed suddenly causing the destructive, dangerous crisis (that plus poor judgement). Recovery ended up costing the owner a lot more than an appropriate rigging fitting would have.With that said I believe these fitting will serve well, with their limitations in mind, and they offer good value in that regard. I can probably smooth the sticky plunger pin out with some rigging lube. They will be employed as part of a lift rig for the dinghy on my boat.

I knew what to expect based on the description, but was still surprised at how heavy and large these shackles are. They appear well made, with no obvious defects noted in fit or finish. I think these will stand up to quite a bit of abuse, and last a long time. They are supposed to be marine grade stainless steel, but only time will tell if they will hold up in the harsh environment of a salt water environment. I think they will, based on initial impression, but again, there is no way to tell until they have been in use for some time. If I have further thoughts after using these for a while, I will update this review.

Review for: Faneta Stainless Steel 316 Swivel Eye Snap Shackle - Marine Grade Quick Release Jaw Swivel Sailboat Shackles - Marine Boat Sailing Rigging - for SCBA Mask & Spinnaker Halyard - Pack of 2, 3.5 inGood set of 3.5 in Quick Release Stainless Steel shackles. Not sure what type of load can be on this, but not a lot. I ran a magnet across this and had very little magnetism about 10%, on the main parts of the shackle. Looking forward to using these on my sailboat!Overall 4.7 stars taking into consideration the products description, quality, features, value and cost of 16.50 reasonably priced. I do recommend this product, and would buy again.

These are excellent “economy” snap shackles. They aren’t perfect, but they work just fine and you could literally pay ten times what these cost for name brand stainless shackles from a marine hardware store.These shackles have a good, polished finish with a few small flaws that don’t impact their performance. They swivel smoothly, and the snap gate closes easily by simply snapping it closed (no need to retract the pin). On one of mine, the pin wanted to bind a bit when pulling on the ring to open the shackle, but it loosened up after using it. Also, if the shackle is open and you pull on the pin before closing it, the pin may not snap closed all the way until you wiggle the hinged gate a bit to get the pin aligned in the hole. Expensive shackles might have tighter tolerances making the pin line up perfectly every time. I also noticed that the fixed shackle end on one of mine (the end with the cotter pin) was pinched down a little narrower than on the other shackle. Once again, high priced marine hardware might be manufactured more consistently.I’ve highlighted some minor flaws with these, but the bottom line is that they work well and look good, and at the price of $16.50 for two 3.5 inch shackles these still deserve a five-star rating from me.
