Default hollow wall anchor setting tool

Hi,

In the past, I have always tightened hollow wall anchors like these:
http://www.toolstation.com/shop/Scre.../sd1930/p53569
using a screwdriver, without troubles.

Today when I did this, I had one anchor spin in the wall and erode
away the plaster, presumably weakening the fixing. It didn't help that
I then over tightened it, pulling even further into the wall!

I have seen fixing tools like this:
http://www.toolstation.com/shop/Scre.../sd1930/p96740

and always thought (wrongly) that when you pull the handle, it must
turn the bolt. I have done some googling and it would appear that
actually they just pull the bolt without rotating it.

Are these a case of you get what you pay for? Should I buy a dearer
brand (if so, which?) or are these cheapies at Toolstation and Amazon
as good as any other?

I just wondered what you had used these anchors to hold? I found
examples on the web of people holding radiators with them and wash
basins. I would have thought these were best into noggins. Surely
something as heavy as a full radiator would be pulled off?

TIA
Fred

the setting tool makes so much difference, I have been using one from
screwfix for years
http://www.screwfix.com/p/setting-tool/12429

was a lot cheaper when I bought it about a £5 IIRC - I sometimes find that
brnging it into a warm house from a cold shed encouraging comndensation on
the friction bearing surfaces which makes it slip a little, you also have
to be aware that the puller is attached to the shaft by a screw which
sometines works looes and can strip its thread if not tightened up - often
hang heaey item using decent sized wall anchors like these - only smallish
radators though -

I bought a setting tool from Screwfix - which looks very similar to the
Toolstation one, and at a similar price - and it works fine.

It definitely *doesn't* rotate the screw - it pushes the body of the
fixing against the plasterboard and pulls the head of the screw away
from the wall - thus compressing the gubbins at the back to be a tight
fit on the plasterboard. You then have to unscrew the screw, pass it
through whatever you are fixing to the wall, and re-screw it into what
is now a very secure captive nut.

Whilst it's always good to screw into a frame member or noggin when
possible, these fittings will take a lot of weight - and are as strong
as the plasterboard. Plasterboard is actually quite strong as long as it
is adequately supported.

I have used these fixings for all sorts of things - including a ceramic
washbasin, albeit on a pedestal so that the fixing wasn't taking the
whole, weight. [I had to buy some longer screws to go through the tiles].

I don't think I've actually used them for a radiator - but I would have
no particular worries about doing so - as long as the plasterboard wall
was sound.

The only limitation I've found is when you need two screws very close
together. They must be a certain minimum distance apart - otherwise the
spready bits at the back interfere with each other. You can put them
*fairly* close if you pay careful attention to the orientation so that
'petals' of one fit in the gaps between those of the other.

That works... but I prefer using the setting tool.

No it just pulls the bolt head using the flange on sleeve to restrain
it. Thereby folding the anchor into its "fixed" position. You can then
take the bolt out and the anchor stays firmly put.

I have a basic cheap one, seems to work ok.

A radiator is fine since most of the load is in shear. A basin would be
a much more difficult load to support on plasterboard since it will have
significant "pull" on the fixing. Might be ok if its the type with a
supporting bracket.

Personally I have done rads, and large flat screen TVs (although that
was in a commercial site onto plasterboard where shop fitters typically
use two layers, which makes them harder to set. Also curtain poles etc.

I used to do that but bought the setting tool and selection of
anchors that Aldl had the other month. Wouldn't go back to the
screwdriver method now, with the tool you know it has been set
correctly not partially set or over done.

I'm going to play with it and plasterboard with foam insulation
bonded to the back as a lot of walls here are like that now. The foam
seems fairly friable so I don't think it will be a problem but I'll
set one or two into an off cut then dig away the foam and see what
has happened.

As for load bearing, they spread it over quite and area behind the
board and most loads are sheer. Must admit I'd be wary about fixing a
wash basin with them but that's more down to the plasterboard
deforming over time rather than a failure of the fixing.

I wonder what the plumber is going to use to fix the radiators to the
plasterboard/foam walls?

You can get them with longer shanks. I had some for years with ~1"
sections before realising exactly what they were intended for!

Also, as an aside, on Friday I used four to hold a 10kg 94" projector
screen to a plasterboard ceiling....

Modern flat with that metal strip stuff instead of wooden joists so I
located the steel and drilled through both it and the p'board. Pushed
the fixings through both, tightened and job was a good'un.

BTDTWTTS, found them to expand and grip without problem.

I'd agree - makes the job painless. Only problem I've had is when using
the smaller anchors - the gap in the jaw is too wide - a washer on the
bolt sorts it.

Thanks. I wasn't sure whether these were like crimp tools, where you
needed a decent one to work, but judging from all the replies, the
cheap ones are just as good, so I'll go ahead and order one of those.
