    I've just ordered a composite door for my garden outbuilding.

    I plan to fix it to the brickwork using 7.5mm concrete screws which seems to be the recommended way to do this nowadays.

    The question I have is what length screws should I buy?
    How far into the brickwork should I aim to go?

    It all depends on material you are screwing into and how far you need to ' reach ' . As a general use 80's or 90's should be ok, that's what we use most of

    I usually use 120mm or 150mm.
    Fixings should go at least 50mm into the block/brick, The frame is usually around 40-60mm thick
