5/16" Bow Shackle, Marine Grade 316 Stainless Steel D-Ring Shackle, Heavy Duty Screw Pin Anchor Shackle for Boat, Sailboat, Chain, Strap and Rigging, 4-Pack

I ended up getting the 5/16-inch 4-pack of these shackles, and I am very impressed with the overall quality. The finish is excellent, with no sharp raised corners or burrs on the metal, and the threads work perfectly on every single one of them.Because these are made from 316 stainless steel, they feature a premium, corrosion-resistant material that naturally makes them a bit more expensive than standard steel. Given that premium build, a 4-pack for $15 is a solid, fair value for the level of quality you receive.I haven't tested their official working load limits for heavy recovery, but for my uses—like camping and hanging bear bags—they are going to be a nice, reliable addition to my gear. I really like this product and would definitely recommend it.

These feel heavy duty, have a tough, smooth to nearly polished surface and just feel robust. They are a good size to be strong enough for a swing set or something comparable to that.I used two of these to attach a too-short replacement hammock to our frame. They work perfectly and are surely stronger than the hammock rope. I could have also used one and a short length of chain.I docked a star because one of the shackles had a burr from tapping the threads that stuck out, was sharp, and poked me. That's how I discovered it. The other 3 were clean.

Good quality, reasonably priced shackles. The pins screw into place easily and have a good friction grip when tightened all the way. All surfaces are smooth, absolutely nothing to cause an issue. These are great for attaching ropes/cables/chains. I'm using them for tree and brush removal or whatever else might come up, they are very handy to have on hand. I like that they are stainless, durable and won't rust. Recommended.
