Abimars Eye Bolts by Load Capacity 1000lbs, 4PCS M10 316 Stainless Steel Eye Hooks Screw in Heavy Duty for Hanging Hammocks, Swing Chairs, Heavy-Duty Suspension

These are even bigger and more useful than anticipated. I can bolt two or more of them to a stud in the wall and run a cable lock through them to keep thieves from taking my valuables.

These bolts are an extremely good value. Exceptional quality as the are very low magnetically. Thus the metal used in their manufacture is 316 or above.

Heavy duty castings, exactly as described! Thank you!

Sturdy bolts for waterproof sail installed from the trees. Looked for stainless steel so I don't poison the tree. These were perfect for the job.

The was exactly what I needed. Too bad I don’t have anything else to hang. Very strong and very sturdy.

It's quite long so make sure you have enough space to install. Had to buy a large enough drill bit to make it work on my wood posts. Looks really nice once installed and held up my hammock with no visible stress at all.

These were much bigger than I expected. If you are looking to secure something to hold a huge amount of weight - these will do the job.

The weight rating, (according to engineering standards) cannot be achieved unless the full threaded length is in a high strength wood (not a ceiling beam or average tree).

I like the 316 stainless steel the down side it doesn't say max wight capacity.
