    Hi there,

    I've got 2 wooden frames (5 kg each with 2 screw holes) which didn't come with screws and I need to hang them up on masonry walls.
    Can you advise what screw lengths I should be using?

    The head of the screws I currently have are TOO big (currently have 3 inch screws) and doesn't fit into the hole of the frame! :-(

    oh ok, thanks.
    I already have the brown rawl plugs but for £6 this item seems decent! Is the rawl plug the same size as brown coloured ones - 7mm?

    P.S. Would 3.5cm screws not suffice!? I have longer 4.5cm screws but the heads too big and doesn't fit into the where the screws sit on!

    According to the spec you need a 6mm drill bit, so sounds like they might be a little smaller.

    5kg into brick isn't much at all - I would say if the screwhead is too large for your frame then go down the sizes until you get the largest one that fits.

    That would mean 3.5cm screws... WILL that suffice or not? I wasn't too sure why you meant with '5kg into brick isn't much at all'.
    I don't have any other screwheads that fit at home so unless I go B&Q where I can compare the screwheads this is the best choice...

    Bricks will support way more than 5Kg is what I meant.

    I'm only a DIY'er so don't take what I say as gospel, but all I can tell you is that if it was me I would go to B&Q or Screwfix and buy a pack of plugs and screws together so that I knew that the screws were a good match for the plugs.

    3,5cm should be fine so long as the plug is a snug fit in the hole and the screw is a the correct size for the plug.

    For a 3.5 screw brown plugs are too big, reds will do but you need a 5.5 or 6mm hole first

    But will 3.5cm screws suffice!?

    I'm talking width in mm and you're talking length in cm.
    What size head fits your keyhole?

    8mm head....

    That's probably a 4mm/8ga screw in whatever length you want although 50mm/2" will be more than ample. Use a 6mm masonry drill and a red plug

    Forgive my ignorance, so is the 3.5cm screw lengths too short as you're suggesting 5cm?

    3.5mm probably fine as long as the rawlplug is not in too deep and is a nice snug fit. Use a 5.5mm to drill the hole and decent red rawlplugs.

    Note I’ll have to have the screw hanging out a bit. Will that length still suffice!?

    Yes my comments above still stand (although its 35mm not 3.5mm:oops:)

    You'll know whether its OK when you screw the screw in - if its nice and tight then fine, too loose and you'll need a longer screw. Its a shear force that's being applied, key here is that the whole length of the screw that's in the wall needs to be supported, otherwise the head end can get pulled downwards and then you're in trouble.

    Screws are measured in 2 ways:

    Width eg no.6 , no. 8 , no 10;

    And length.

    There are multiple combinations of the 2 dimensions.

    OP is talking about a screw that's 35mm in length.

    Thanks all, finally put them up a month ago! So difficult with the frame holes being in different places and drilling into cement rather than brick (guessing game)!!!!
