dot and dab fixings

[chunkolini]

a weird one.
For years I have used the plaster board fixings that use a cast alloy screw that goes into the plaster board and takes a screw from the front like these. (stoppit at the back)

my old kitchen was held up by them, on stud walls.
I just came to fit a coat rack on my dot and dab wall using them and nothing doing the ally screws just spun in the wall. It stayed up but no way was it secure.
I was thinking rawl plugs and long screws but could see the plaster self destructing.
These look like they are made for the job. Pricey at about a pound each but well has to be worth it? Id go for the countersunk versions any other options?

I used to use off cuts of 15mm copper pipe cut to the board level to stop the board pulling in

If they're the ones that go through the plasterboard and span the gap to the brickwork they are very good.
I've got a column radiator hung on some of those.

 

[Agrismith]

I have the cheaper ones without the metal tube.
I use them in the dot and dab and never had a problem.
Im to tight to buy the red ones when the grey work for what I need to do.

The Hammerfix is led through the component in the time-saving through-type installation. When driving in the nail screw, the fixing...

To quote one of my favourite sayings “you could anchor a ship to that”

For light-ish stuff I like the Fischer Duo plugs (grey/red)....they expand in the gap I believe.

Rawlplug do a special hollow wall fixing with a tool to fit them....basically like a rivet nut. I've used those and been happy.

I have some that you put in and expand with a thing that looks like a pop rivet gun.
If you google cavity wall fixings with setting tool, it beings up various options.

used to be called fast brolly fixings and you could get the gun for setting them

 

[MetalMonkey]

If you have sufficient space in the cavity you could use a hollow wall anchor, or a fisher plasterboard fixing.
Or the duo plugs as Mr Droppings suggested.

For anything heavy, corefix is the way. And yes they are pricey.

I was trying to remember what they were called. A lot of kitchen fitters use them now and with the gun saves a lot of time.

One disadvantage of the brolly fixings is they are difficult to remove without damaging the plasterboard.

Knock them in to the wall. Fill the hole!

 

[mtt.tr]

I use the threaded ones on light loads

Anything with substance I just go over to the expanding oven that require the tool.

Bigger still I'll drill into the substrate and use plug

Hollow wall anchors, is the technical name I believe

 

[lazybones51]

I've used the ones in your second photo with the metal tube, they're very good (but not cheap as you said). I think they're about as good as you're going to get, as you're fixing in to the wall not the plasterboard.

 

[Pigeon_Droppings2]

I only use the plugs and hollow wall anchors for light stuff.

Anything heavy like a radiator or large TV I switch to resin and threaded bar. Also I don't trust plugs when the wall is made of light block...compressive strength is poor I think. Brick or heavy block is usually fine.

 

[Cobbler]

Those fittings similar to the Brolly fixings that Brightspark was on about are or were in the centre aisle at Lidl’s. A kit of various sizes & the tool for setting them, I’ve use them without the tool without difficulty though.

I have just used a load of the bottom ones with tubes, nothings fell off yet, I feel they are worth the £1 each.

I've always known them as Mollys
They are brilliant though
I've used them for hanging radiators, with glue on the bracket as well,
with no issues, as well as kitchen cupboards and the like. Plasterboard
is (can be), very strong when the application technique is correctly
followed

 

[chunkolini]

cheers all
I think the ones with the metal inserts. I only need four of them on this wall.
