What not too sticky sticky stuff?

I am trying to fix some monitor swing arms at work as the monitors are a bit too heavy for the locking mechanism to successfully lock them in place and they keep drooping down. I was thinking about some kind of rubber shim however the fixings are way too snug to fit anything like that.

An alternative would be to glue them with something like threadlock however I don’t want the position to be permanently fixed so I was wondering if there is such a thing as a sticky glue-like substance that doesn’t permanently bond?

For reference, these are the monitor arms:

Easily sourced if you relax your at desk browsing policies too.

You can get non-permanent threadlock.

Really though, if you’re exceeding the load rating of the mounting bracket you should be using a bigger mount.

What about carbon gripper paste? Halfords do a little tube for £3 so it’s easy to try.

Easier said than done. And to be clear – they are generally okay, but over a year of an empty office and about 30% of them had failed and it’s those that won’t seem to lock back up securely. It’s not like they are massively too heavy, just at the extreme of the capability of the mount. And I’d really not want to landfill them when there might be a decent fix available.

loctite 243 is non-permanent i think.

i can’t really picture how it works, are you asking for something to hold the the sliding mechanism in place?

would a well placed bit of helicopter tape undernesth the slidy bit provide just enough legde to prevent its slipping down?

The silver disk behind the monitor (the one with the writing and arrow on) is the mechanism that allows the monitor to angle but it doesn’t quite grip hard enough to stop some monitors from drooping down.

Do what I do at work and put a whiteboard marker in the slot so it doesn’t drop down. #protips

Threadlock might work if you can hold them in place long enough for it to set.

Or a bit of string from the arm to the top…

Are you sure there’s not a hex bolt that controls the friction of the mount?
They look really similar to ones we used in the office I used to work in – which had hex head adjuster.

I was going to post about the hex adjuster too – I think I can see one. Get an allen key on it and give it some grrrrrr.

A wrap of PTFE tape? Squirt of Scotch Mount? Might be easier to suggest something if we’d a better idea of how the mechanism locks, I was assuming a through-bolt that you tighten.

Potential manufacturing defect, then? Might be worth contacting the manufacturer, see if they have a supported* fix?

(* – ho ho!)

Blob of superglue ?

Presumably there’s some sort of friction disk / clutch type thing in the mount that’s slipping? It’s not just a bolt that slips.

You could rough them up a bit, but you’d also have to shorten the bolt/spacer a bit to pull them together tightly again. Or just shorten them and figure out what enough torque is to load the clutch enough to give enough bite.

As above, that very much looks like a tension adjustment in the pic. Fetch your Allen keys.

Believe me I have given them plenty of ‘grrrrrrr’ LOL!!!

Yeah there are two parts – an alloy ‘male’ with a slightly rough surface and a plastic ‘female’ (the part that has the bolt-though tensioner on it) that has a really smooth surface. I think that simply having something grippier (like two rougher surfaces) would be enough to make them bite.

Skateboard deck grip tape cut out and placed on both sides of the friction discs?.

Plumber’s Mait
Non-setting and it sticks to all sorts

carbon assembly paste ?

Either Sugru, which sets solid, or black tack, which is like a much stronger blue tack, photographers use it to hold stuff in place.

Glus some wet and dry sandpaper onto the slidey nylon 66 washer. Will move but the friction will be increased hugely.
Failing that, stair edge grip adhesive tape. Its like 40 grit sandpiper so won’t slip.
