I want, somehow, to attach an eye bolt or eye screw to the end of a metal tube. I'm wondering how to do this most easily? The construction needs to withstand some pull in the tube's longitudinal direction, so something that creates friction against the inside would be preferred. The tube's inner diameter is 15.2mm
or
in here:
Solutions I've considered:
Expander that grips the inside of the tube. Simple solution but I can't find anyone who sells it, maybe I'm searching with the wrong term?
Epoxy. Don't know how strong the tensile force it can withstand, but I think it should work.
Welding a washer with a nut on the back (perhaps easiest but I don't have a welder).
Grateful for input and also tips on where a potential expander is sold (preferably online).
You could also make a hole in the eye bolt and a corresponding one in the pipe, then drive a pin through.
True, I hadn't thought of that. It will have good tensile strength anyway. I do want the bolt to be fixed so that it can't move, which can be achieved as long as the bolt diameter matches the inner diameter of the pipe. The only downside is that the pin sticks out from the pipe and since it's something meant to be gripped, it might interfere, but good suggestion. Thanks.
How should it be used? Do you have access to the other end? You can run a threaded rod through and put a nut on one side and an eye with female on the other.

I like the idea, but the whole device is like a telescopic handle, i.e., the length of the entire rod is not fixed but variable. Good solution otherwise.
I have access to both ends (should be eye bolts in both) but variable length as mentioned.
A star nut for bicycles should work well. Depending on the dimension of the tube and thread.

How does it function mechanically? You push the part with wings into the tube, and the wings press against the inside of the tube when you screw in the bolt? Otherwise, a neat solution. Do you think it holds for much force, say hanging 20kg from the ring in the tube's lengthwise direction?
Weld...
If there is no one in your circle of acquaintances who has a Mig or Tig welder, most older/smaller car (workshops) have a welder.
Takes a maximum of one minute to fix.

Heheh yes precisely. it is undeniably the easiest... maybe suddenly got a good reason to get a welder
How does it work mechanically? You push the part with wings into the pipe, and then the wings brace against the inside of the pipe when you screw in the bolt? Otherwise, a neat solution. Do you think it can hold a lot of force, say hanging 20kg from the ring in the pipe's length direction?
I actually don't know how much tensile force such a thing can handle. But 20kg doesn't seem like a problem offhand. However, I would see if someone can weld in a washer with a nut. Where in the country are you located?
