    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. :)

    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.

    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...

    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

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

    I started in the trade many moons ago and all we used were rawlplugs they never let you down , one thing I do find awkward sometimes is type of screw as in the good ole days they were all tapered ie black Japaned or slotted now all seem parrellel .
