Is there such thing as an open eye bolt that's also shouldered?

I'm trying to accomplish three things with this fastener:
1) have a predictable height (hence the shouldering)
2) allow a chain link to enter (hence the open part)
3) not have to use additional quick-links that take up space (otherwise I could use a closed eye bolt)

I looked online and an eye bolt is either shouldered or open but not both. Any other type of fastener come to mind that's not a screw but a bolt system?

TIA

Did you check McMaster -Carr.
If you can't find an open shoulder bolt use a fully threaded shoulder bolt and cut out a section of the ring to make it open.
edit: As long as it won't be used for lifting or have ant tension this be OK

You can also use a fully threaded open eyebolt and run a nut to the top and use that as your shoulder.

I checked McMaster-Carr, I order from them from time to time. They don't have it.
Cutting may be the only option.
I've tried using a nut as the shoulder but within the same dimensioned bolt there is variation on how high the nut will go up so if I have several of them in a row they will not be perfectly even

Not surprised if they were imported (China or Mexico). You need to get US made and be sure full threads are cut to the same height.

I've never seen a shouldered open bolt, since most shouldered eye bolts are designed that way for strength. And an open side defeats the purpose.

Similar to shouldering the nut, you could use a nyloc nut as the shoulder and use a ruler or calipers to adjust it for each eye to be perfectly matched. Maybe a bit more work, but I don't see why you couldn't get it easily within 1/16" or 1/32" accuracy that way.

If I can't have a shoulder then I might as well use an L-Shaped bolt.
I would confirm first that the USA-made ones have exact threading.
I want my product to be made in USA and if I use foreign components then it's not really (I think)
