    Help! Above boiler needs H/E cleaning or replacing but looks like some one tried before and they have completely burred the inside of the screw. The screw looks like it has an 8m external socket head but less than 1mm protrudes so can not get a socket on. Any one with any idea how to get these out please?

    File the face off the socket to get rid of the chamfer.

    Now that did cross my mind, is that something you have successfully tried before or a guess (before I ruin my socket set!)

    Or a box spanner / wera hex driver

    And yes cutting the socket down to get full square works well

    Not on that appliance, but on other things.
