Red and brown plugs ..radiator fixing

[Phil]

This is interesting, when fixing a rad I tend to not use the supplied fixings and just use my own. I use Rawlplug Uno brand as I think you get a really good grip.

Any Rawlplug nerds will find this video interesting.

Best plugs are Fischer’s in my opinion

 

[townfanjon]

Never used them. What sizes do they come in.

I've found B&Q's own brand Diall excellent believe it or not, you can't see it on this link but they have a square head so don't spin.

More than quiet good they're quite good or very good I'd say

Not tried those , do they sell square drills .

Usual brown for 7mm holes but the next size up is 8 mm ( blue) so if the brown one isnt tight enough the blue ones fit spot on . Never seen any smaller ones but they may do them , I have never looked .

I love the Uno brown plugs and find they grip well due to the way they expand and also they work with narrower screws, like for pipe clips etc.

One thing annoys me about plugs is most of them are very short and it is silly when you want to use a 50mm or longer screw when the plugs are little more than 30mm.

I just watched most of the video.
He didn’t need to test the plugs grip. It was obvious that the red plugs have more grip than brown if screw is heavy gauge for the red plug.
We all know this when we try to use a hand screwdriver on heavy screws in red plugs.
I see a lot of plumbers and electricians use mainly red plugs.

Why do you think that is?

Why do you think that is?

Then if the wall crumbles away they just bang a brown in

Do t have a clue Harv

I've a mate (not a tradesman) who's less capable than he thinks and can't drill and plug to save his life, normally this would be grounds for divorce but he's a decent friend. Anyhow, when I've been over to help I've noticed how he does things which include using the cheapest plugs available (plain sheeth type) while also clearing out every drilled hole throughly (therefore removing most of the masonary grit and making the hole larger). I mentioned the flaw in his technique a few times as I was able to pull them out with relative ease but it seemed he took no notice. After moving in to a new home, queue a few months later and he's been to Ikea to pick up a few storage units that can be wall mounted above head height usually above a TV, stereo etc. Yes you guessed it, when fully laden the whole lot came crashing down a few hours before the start of his house warming destroying his £2.5k imac and several grands worth of music system. Tit.

I think he's being serious Harvest, what do you want to use a 2"+ plug n screw for? What the cock are you fixing to the wall that requires that sort of anchorage, your Mrs' handcuffs?

Seriously on the odd occasion you need some extra length, double up by cutting the flange and tapping an extra one in.
Yes, yes, snigger, snigger I'm being serious ffs.

Edited due to me not reading the responses properly.

I was thinking of heavy radiators into solid walls that are perhaps with a 1/2” layer of plaster and also maybe weak wall or drilling into joints.
A 40mm screw into a standard length plug is barely gripping.
I punch some plugs further in past the plaster to give rawlplug chance to grip solid wall.

7mm Hole, Brown plugs, 2 1/2" 10's.

 

[quality]

Red Plugs 2 1/2 x 10 screws

 

[Ben-gee]

I'm not surprised at his test results as he drilled an 8mm hole for the brown plug, which surely should have been 7mm?
Same as Best, i drill deeper and 'push' the plug in deep by hammering screw into it, then tighten with driver. It never fails.

What was that crashing noise.......

 

[ShaunCorbs]

5.5mm for red
7mm for brown

8-10s for reds unless hard brick (more likely to snap / crack the brick with a 10 screw)
10-12 for brown

around an inch setting depth for the plug

Snapped a the odd screw but never cracked a brick

There's some Burnt hard engineering brick that don't like to be core drilled them ones snap with a 10

...or when Best is using a 3" screw with 200Nm impact driver to fix a pipe clip.
