Abimars Eye Bolts by Load Capacity 650lbs, 4PCS M8 316 Stainless Steel Eye Hooks Screw in Heavy Duty for Hanging Hammocks, Swing Chairs, Heavy-Duty Suspension

Worked great for what I needed , drill a pilot hole before screwing in

In the past, I wanted to get my riding mower up on blocks to work on the deck. The heavy end is 200 pounds. I bought a 500 pound chain hoist and an eye bolt rated at 2200 pounds to attach through a 4 x 4.I saw that hoisting an ebike could make work easier. If I used a rafter, I wouldn't have to set anything up as I did with the 4 x 4, and I could work under cover. I tried a 1/4 inch eye bolt that could be secured through a hole to a washer and nut. The drawbacks were obvious. It was rated at 100 pounds, which would limit its use. Horizontally, it could bend with less than the rated load. Besides, a bike hanging from one point would be unstable.I bought these, rated at 660 pounds and pointed down to avoid lateral force. I've read that a 5/16 lag screw will hold against 1,000 pounds. I chose a pilot bit the same size as the minor diameter of the threads. Then I used a larger bit for a snug fit on the shoulder, marking the bit with tape so I wouldn't go more than an inch deep. The snug shoulder helps protect the threaded portion from lateral forces.One photo shows the chain hoist clipped to one of these eyebolts, a few inches from the undesirable 1/4 inch eyebolt. Another photo shows the chain hoist roped to a point where it takes most of the bike's weight. I used parachute cord to hang the handlebars from another eye bolt.In the photo, the tail of the chain is in the way. To hang the excess chain, I put a lag screw two feet from each eye bolt. The third photo shows that the lag screw is also handy for tying off cord used for hoisting. Here, I hoisted the handlebars to get the front wheel a foot off the ground to facilitate checking and adjusting spokes. Three lines suspend the bars. If that end weighs 21 pounds, there's only 7 pounds of tension of the cord, so there's not much lateral force on the eye bolt. I found that if I tipped or turned the bars, cord friction would hold them where I wanted.A chain hoist is safer for heavy loads, but for something pretty light like an ebike, a cord is quicker to set up and it lets me raise the load to the rafters if, for example, I want to work on a derailleur. Hoisting a bicycle or similar item would also allow a wheelbarrow or mower to be parked below it.

Good quality. Used in ceiling to lift jeep gladiator hard top

We are using these for hanging hammock chairs. As described, thanks!

Bought stainless to replace rusting plated 5/16-inch-shank screw eyes. These are 8 millimeters shank, so ought to be quite close, as 8mm is actually slightly larger than 5/16 inch, but they are not quite 8mm. so seem a bit loose in the old holes. The shoulder is an improvement on the old screw eye which had no shoulder, as it allows compressing a washer onto caulking around the penetration. Threads on the old eye extended beyond the shank diameter; on these the threads do not. The packaging fails to identify the material as 316 stainless, fostering uncertainty.

I really like this product.The stainless steel used with stainless steel hooks provides a quick, quiet way to hang a swing.

Quality stainless & my bears will be very unhappy

To hang out hammock up.
