HELP!? TV Wall Mount Fail?

Submitted by TheNorthernSaint t3_113nasy in DIY

TLDR: I fit my wall mount tight and secure but the wrong way around, I had to then re-do the job and the wall bots are not tightening. Is there anything I can do to make it more secure without moving the location of the mount? Any help is much apprecieted!

Last night I mounted my 55" TV however the wall bolts will not tighten.

I began by measuring everything up then drilling a test hole to find the depth of the dot and dab plasterboard. I then assembled the mount, placed it perfectly and marked up. After drilling 6 holes to match the plate I put the plugs in, placed the mount on the wall and then screwed the bots in a little to catch the plugs and then hammered them in as far as they would go into the wall before tighening solid.

Job well done!

.... Well no, the TV mount was on upside down! (I could have sword I had checked but evidently not)

I had to then pull everything off taking out the screws and delicately pull the plugs into the plasterboard to hold them in place before fitting again.

The big issue is now only one of the 6 bolts will tighten fully. The rest just keep turning.

Plugs at 10mm and about 80mm long and the botls are about 12mm long.

**My question is: Can any of you please help or advise on a fix for this without having to move the location of the holes as it really is perfect center on a small width floor to ceiling wall**

You hammered the bolts? I’m no expert but I’m pretty sure bolts are never meant to be hammered. Only nails get hammered. You probably broke the anchors, or plugs as you called them. I could be wrong though.

It was just to get them to push through the plaster and gap and into the brick before then scrwing them in for a tight fit.

You get bolts for brick and concrete that are designed to be hammered in first.

Trubolts and Thunderbolts are a couple of examples.

The plugs (anchors) that come with TV mounts are only to be used in masonry. You need to mount it into the studs for a drywall application. Lucky you messed it up the first time, because it probably would not have held.

Its just dot and dab with masonary behind it. It is a new build home though so unfortuantely its breeze block that is the layer I was going into and crumbles way too easily.

That mount needs to be securely fastened to the wall studs.The insert hangers you used will fail

I would suggest you cut out the wallboard and put 2x4’s between the studs where the mount holes are and secure the studs. Then patch the drywall and get some 3” screws and secure the mount to the 2x4’s. There is no drywall molly, toggle, etc that will stand up to time.

No studs.

CMU wall with paneling on top of that.

You could possibly put some wood there. Like attach few pieces of wooden board (or one bigger one) there -> bolt it to wall -> bolt tv mount on top of that.

Or instead of wooden board, use metal (like this). Mount it to wall from corners, so one hole in the middle will match current hole. Metal plate should help secure the current holes.

But really, I would maybe leave this to professional to prevent more fuck ups. Or just move it 10 cm higher and use mount with movable arm, so you could put the tv lower.

Edit: Or just use bigger screws.

Thanks for the advice. I think move it or go for slightly longer / bigger screws may help.

Reading between the lines, it sounds like your wall is plasterboard (aka drywall) glued directly to a masonry wall. What is the underlying wall made of?

Do you think you hammered out the breeze block? If you put in the plugs and then hammered them as far as they would go, the breeze block may have failed on the back end. I would suggest repositioning the mount a few inches in either direction that fits your layout. Drill new holes and use masonry/breeze block anchors.

How many bolts are supposed to go into the wall to hold the bracket? (You said you had 6 that held firmly)

...any idea of their weight capacity, or of the total weight for the TV + Bracket?

If it’s concrete than use tapcons. Just make sure they don’t go into the hollow portion or they won’t bite.
