Which Type of screws to use when wall mounting?

[Neil N]

hi,
just bought a 32" Sharp LC-32GA6E. I am planning on mounting it on a external wall (plasterboard then breeze block) Any ideas which type of screws would be best to use?

I have looked at this type but not sure ( http://www.screwfix.com/app/sfd/cat/...01151&ts=89886 )

Any help would be much appreciated

Thanx

For platerboard walls with anything heavier than picture frames (like bathroom cabinets and radiators) I've always used these

When mounting on an external wall, I predrill with a 5 mm wood drill, then swap the bit to a 5 mm masonry bit and take a few mm of brick out... otherwise the the plasterboard gets pushed away from the wall as you tighten the readidriver - they're just slightly longer than the gap between the plaster and the blockwork. Buy a 100 pack and then give some to your friends - they'll be ever greatful.

That said, the most expensive thing I've mounted is a £400 radiator (using only 4 screws), but I'd be nervous about hanging £1000+ of screen on plasterboard, so your original solution may not be overkill. Just make sure your not going through any gas pipes, cables or the fireplace flue

if its a solid wall, get some big heavy duty wall plugs and some big coach screws.

these can be bought from B&Q, well assuming you live in the uk.

I used 2 sets of 6 x M8 coach bolts for mounting my 32" LCD ... these matched in strength those supplied with the bracket so I guess it is an indication of the type of bolt used. 2 sets were used due to the sandwich nature of my setup - one set for the batton and another set for the bracket itself. It was possibly a little over engineered - the fixings for the bracket would take up to a 37" display with glass front, but I played safe as using smaller fixings would save me nothing and my sandwich design meant that the weight of the panel was a couple of inches forward of the stud possibly creating a slight rotational force where the batten joins the wall.

I posted my experiences here.

Its still as solid as when I first put it up.

For plasterboard, you definately need to use battons attached to the nearest secure studs. If you do take a look at the photos, I think that the size looks deceptive - it is a 6"x2"x~20" batten and I used large M8 x 60mm coachbolts and the supplied screws for the back plate. The wallmount itself is 11"x6". I think my biggest tips are to survey the wall for studs and noggins, pre drill the holes to prevent the wood from splitting and of course make sure that all A/C power is disconnected in the area - my stud finder had an A/C power finder that was indicating mains radiation from the wall but would not accurately pin point it.
