SHONAN 3 Inch Stainless Steel Chain Quick Links- 4 Pack 5/16” Large Locking Carabiners Heavy Duty Chain Connector, 1535 Lbs Capacity

I use this to keep the lid closed on an outdoor garden bin. No rust even after a few months of frost, rain, sun and sea air. The threads have not deteriorated either, screws on and off as easy as brand new.

These are best I have found - nice packaging - really high quality with no manufacturing flaws

One link locked up after unscrewing it all the way. Two other links locked up after screwing them shut all the way. A wrench wouldnt work. Tried WD-40 on them, but that didnt work. Had to use a bolt cutter on the two that locked while screwed shut. If we hadnt had a bolt cutter, it wouldve meant our pet being stuck in a cage, because we wanted to use the links as extra security while we were out of the house.

Very well made. I’m impressed with the quality.

Sturdy.

Worked well for my project. No issues.

Quality looks great for the cost.

They worked as advertised ... I used them on an outdoor canvas saddle cover, and they were well built. Good bang for your bucks ... enjoy

Works well, used for links in my lunch box cooler strap

High quality
