Hello!
Renovating the staircase and have removed the handrail. It was a regular top rail, attached with some clumsy homemade wood construction. (Poorly but picture 1) When I removed everything, there is still a handrail bracket left (as it seems). A cylinder that is firmly in place. I am attaching photos of the cylinder. It is threaded inside and there was a large screw in the threads that easily came out.
Now to the problem: the cylinder refuses to budge. It cannot be unscrewed with manual force or various tools. As seen in picture 2, there is a very wide slot at the bottom, and even that doesn't move with a screwdriver, the strongest in the family has tried.
What IS this, I thought it was a set screw, but it doesn't budge a millimeter when we try with a screwdriver in the large slot. How do I remove the bracket? It's set too low to use for a standard round handrail. Does anyone have any ideas?
Then only more violence remains!
Try using a pipe wrench and it will definitely come loose. Alternatively, a striking screwdriver with the largest suitable slot bits.
The execution still makes me think that the internally threaded sleeve and the screw it is in are two different parts. Try applying force to the inner screw. A thin chisel-like tool that fits into the screw's slot and an adjustable wrench with a long handle for this?
Tested pipe wrench now but it doesn't budge. Yes, I also think that the hylsa is screwed on in some way. But the strange thing is that the groove at the innermost part is so damn wide, not made for a regular screwdriver. You can get a grip, but it's almost like the screwdriver will break without anything happening.
I, like justusandersson above, also believe that it might be two-parted. That is, the slotted screw holds the external sleeve. If you try with a pipe wrench tomorrow, it will be self-marking....
Regardless, the screw is likely to have less friction and release more easily if you manage to wiggle the sleeve a bit.
If it's a composite screw sleeve, it will release with more force.
If it needs to be removed, you can take a torx or hex bit that is slightly too large and hammer it into the outer part with a sledgehammer. Then use an impact driver and it will come loose. We used this tactic on track bolts (Strf 90) that were stuck (but with a socket). However, this will not work if the construction is two-part (socket + screw). In that case, it's better with a proper screwdriver and wrench. It's strange, though, that it doesn't move at all if you turn it with a pipe wrench. A divided construction should start to rotate because it can't be that stubbornly stuck, can it?
Tried a pipe wrench now but it won't budge. Yeah, I also think the sleeve is screwed on in some way. But the weird thing is that the groove inside is so incredibly wide, not made for a regular screwdriver. You kind of get a grip, but it's almost like the screwdriver will snap without anything happening.
Apply more force or use a larger wrench!
All types of expanders that can't be removed have a nut as a lock.
The last resort is to saw off and fill, which you don't want, so apply more force!
The worst that can happen is that you have to saw and fill.
Ok, thank you so much for all the tips. The neighbor came over with a huge pipe wrench, and the SOCKET came loose!! Now I can surely find some kind of upward-bent fitting where the protruding remaining screw can be pressed in. Oh, I'm so happy. This forum is the best! <3
I have something similar for my railing
It's probably a French screw model into the wall with maybe some form of glue on it
Then there is a pipe sleeve that is threaded that the railing is attached with a bolt
Just saw that it got sorted out
CONGRATULATIONS
