Hello!
We have a typical Northern German problem – the weather is changing and it’s getting stormy here.
During the summer temperatures today, we set up and used our brand-new ( 🙁 ) cantilever umbrella.
Now, in the evening, we wanted to close it, but when turning the crank counterclockwise, the umbrella doesn’t close; instead, the crank handle comes off in our hand.
It unscrews from the thread.
There was a small screw inside, which we tried to screw back in, but when turning counterclockwise again, it just falls out.
This is our first (and probably last) cantilever umbrella. Can anyone give us quick advice on how to close it without the crank, preferably without damaging it?
I couldn’t find any useful information on Google.
If I leave it open, it will probably end up three properties down tomorrow. 🙁

Does screwing the crank onto the shaft work? If so, you can try the following: Screw the crank onto the shaft, then place the small plate, and try to turn the small screw into the thread WITHOUT a washer (yes, I know, that's not recommended). It might be that the missing washer is enough to allow the screw to find some thread. If this works, unscrew the screw, apply enough threadlocker to the screw’s thread, and then screw it back in. If you want, you can also apply threadlocker to the shaft’s thread to additionally secure the crank against loosening when closing the umbrella. This wouldn’t be the ideal solution, but it could work and hold for a while.

Yes, I tried it, you can pretty much push it in and pull it out with your finger without much resistance; it doesn't hold anymore as it is. If it’s that loose, nail polish won’t help; only a new thread with a new screw or a strong adhesive with the existing screw will work. When exactly do you need to open it again? The risk of a permanent bond isn’t that high, and the effort is manageable.
Before that, I would try a longer screw—it’s possible that the threaded hole is deep and a longer screw might still hold.

Maybe the missing washer is enough to let the screw catch some thread. If that works, unscrew it again, apply enough threadlocker to the screw’s thread, and then screw it back in.

I can fully push the screw into the thread without the crank (just by pressing it with my finger) and pull it out again. There is hardly any resistance.hampshire schrieb:

What exactly should I search for on Amazon? Or would you tend to recommend the adhesive method? I’m not sure if glue would hold. Right now, the screw has very little resistance and quite a bit of force is applied when tightening it.tomtom79 schrieb:
Respect—7 pages about one screw 🙂 If you don’t dare to repair the thread yourself, maybe someone from the forum near you can do it? Otherwise, ask around your circle if anyone is a toolmaker or industrial mechanic.Mainly, I don’t have the right tools for it (and I don’t know whether I should experiment or just return it). Unfortunately, I can’t find a replacement with the same price-performance ratio anymore. Those in the same price range look much less stable. And I don’t want to spend more money on a temporary fix. Our “broken” part is unfortunately no longer available.
