Hanging Heavy TV

[Sam Gangee]

You glued a TV to plasterboard? I hope your insurance is good. They look for any excuse not to pay out.

I tend to use these, the Easyfix Self-Drill Plasterboard fixing, mainly as I have a box full, however if I hit a batten then I can use same screw, so they all look the same.

I have never seen it published what weight can be hung off plaster board, I would guess no one would stick their neck out that far, as if it gets damp then it will not hold, the idea of a fixing to stop a shelving unit from falling over is one thing, hanging weight off the wall is something else. The 43 inch TV I have I wanted where part of the bay window is so could not hang off the wall if I wanted, but the TV stand I have to admit makes everything look so much neater as there is some thing to hide wires and hold set bottom boxes, don't know why called set top boxes as all the sets I have would never support a box on top of them?

But I have a DVD, and a satellite box and hard drives below the TV all with cables. So the central post of the TV stand hides all these wires.

I tend to use Dryline Pro on "dot n dab" and Grip it fixings on studded walls to hang radiators etc.

Are you so young to have never seen a CRT TV, or have you just forgotten?

For one monitor I had a special shelve, and the old BBC monitor was a steel case, but these were monitors, not TV's most the TV,s I had were in a sculptured case designed to make them look nice, and not suitable to balance anything on the top of them. We as I am sure most other people wanted to use video recorders so had a cabinet designed to hold these below the TV, although there were some small boxes, most I had were far too large to go on top. The Sky box was as big as the VCR and wall mounts had a special bit below to hold boxes.

So although there may have been the odd box which could have been balanced on the odd TV, in the main they have been placed below the TV so an underset box would describe most better than set top box.

It is helpful if you have the Special Tool for locating studs.

A knuckle for knocking on the wall and a magnet for locating the plasterboard screw just below the skim?

Some pathetic houses are built with foam-core plasterboard panels and no studs.

Well, they're probably not that pathetic when one looks at the gas bill..

Indeed, just a single number 10 screw has a shear pull-out load of 687lbs (311kg in English!!) when screwed into softwood.
edit: they don't seem to give the length of the screw though!

What's "number 10" in English? (5.0 I think...)

I'm not sure I understand the "shear pullout" quoted from the article. To me, shear is when a vertical load snaps a horizontal screw, and pullout is when a horizontal load pulls a screw out of the wall. The article is gone now, at least my browser won't load it- so what's shear pullout?

4.826mm actually!! (because it's 190 thou' for a number 10)

To me, shear is when a vertical load snaps a horizontal screw, ... ... ...so what's shear pullout?

Yeah, the article has gone, but from memory the test was a half inch board, screwed into a softwood stud, then the load applied downwards on the board. So, the screws didn't snap, they pulled out of the softwood, downwards, while under the shear load. I hope that makes sense!!

Just ripping the screw out of the softwood stud horizontally, I would normally called that the 'pullout strength', I agree, but I guess you can see where they are coming from. Maybe 'axial pullout' betters describes that type of test.
