Hello!
I have bought a wall mount for my TV that I'm now trying to install on a concrete wall. The house was built around 2010. I'm stuck and simply don't understand what I'm doing wrong!
I have drilled 6 holes with a 10mm drill bit, which according to the manual should be 6cm deep, and then inserted the accompanying plug meant for concrete walls. I have measured all the holes to be 65mm or deeper.
When I try to drive in the screw and mount the bracket, I only get halfway with the screwdriver before it starts slipping. If I switch to a manual screwdriver, I get a bit further, but the screw's slot gets worn out before it's fully in.
After looking around on YouTube, I got the idea that I might not be inserting the plug deep enough into the hole, so I screwed a screw in a few centimeters and hammered it in. The result was that the "head" of the plug (see image) went crooked and broke. Therefore, it doesn't seem like that's how this type of plug is meant to be used.
If I insert the plug into the wall without the bracket and use a wrench to drive it in, it goes all the way in perfectly. I therefore assume that the issue isn't due to drilling too shallow. However, the same thing happens as when I try to mount the bracket if I use the screwdriver or manual screwdriver, which I think indicates that I haven't drilled the holes at an angle.
Since most of the screws are already heavily worn, I realize I need to buy new ones before making another attempt. However, it can hardly be the quality of the screws but rather the knowledge of the person using them that's lacking. If it hasn't been clear from the text so far, I don't usually describe myself as "handy." Therefore, I'm wondering if any of the experts here on the forum can point out what I'm doing wrong?
Thanks in advance!

Plug for 10mm hole usually means a screw that is 6-8mm. Is that what you have?
Set the screwdriver to "drill mode" and go ahead.
And it's enough to fasten with two screws, but use four so it becomes symmetrical and nice...

You might just have too large a dimension on the screw so that the plug expands and grips too quickly?

The screw is 6mm in diameterMathiasS said:
The screw is 5.5cm long and I have measured the holes to be 6.5cmE etompau said:
Both the screw and the plug came with the wall bracket

Ok, maybe you have poor tools or the screws are of lower quality, not uncommon if they come with a TV mount or similar (applies also to the plugs).
Buy new screws, and ensure that you have a screwdriver/bits intended for the screw type. Torx is good, as you get a solid grip with the screwdriver/driver.
Is it real concrete or lightweight concrete?
Always throw away the included screws.

Most likely because the screwdriver is not powerful enough for the task.
(I assume the torque setting is at max, and it is geared down to slow.)
Two alternatives have been suggested to solve the problem:

Two alternatives have been suggested to solve the problem:
- Set the screwdriver to drill mode. (You’ll quickly notice if this works. If not - see alternative 2)
- Buy a socket wrench or ring wrench (preferably a flexible one if it's tight).
Probably the screwdriver won't handle it. How many Volts is it? It can vary a bit but 12V is probably too weak. 14.4 might work, 18V will handle it without any problem. That is my professional experience in fastening larger screws in cast concrete.
