Right screw in door casing insert for hollow brick?

[Ironside]

Used a 5.5 mm concrete drill but strangely enough, there were no hollow blocks? They seem to have used a lot of different materials in these walls. What I drilled into now offered some resistance (probably not siporex) and when I screwed in the screws as much as I could with a straight torx screwdriver, it held the pressure. Felt like the construction became surprisingly stable.

Will definitely continue using these sleeves! Let's hope it holds in the long run!

Installed a new door today with adjufix sleeve, this time I needed to adjust after the frame was in place. A couple of sleeves needed to be shorter which means you have to turn counterclockwise, which in turn loosens the screw that goes through the sleeve and straight into the wall!?

So how is this supposed to work.

Gluing is not an option?

You should adjust the frame with the sleeve before you screw it in.. The downside of concrete screws is that you only get one attempt (or I'm just useless.. ) very easy to strip the hole

In this case, we had unpacked the frame set a couple of days before the job, which turned out to be a bad idea because the frames had warped. When mounted in place, the frames bowed inward in the middle, and to fix this, the frame sleeve needs to pull towards the wall, which of course puts high pressure on the screw. The screw itself has no problem handling this pressure in this case, but when you turn the frame sleeve (counterclockwise) to adjust, the screw becomes loose?

Regular frame screws do not have this problem; they can be adjusted in any direction without affecting the attachment to the wall. It doesn't seem reasonable to need to glue; I must have missed something about how a frame sleeve is supposed to function during post-adjustment?
