    I’m not sure what the name is of the thing I need, but as per the photo I need to be able to tighten (with a drill or electric screwdriver) this hex bolt, but i need a bit that is hollow and long enough to allow for the screw part (1-1.5inches) if that makes sense?
    I’ve not been able to find what I need online but may not be searching for the right thing
    Any help much appreciated!! Thank you

    You need a ring spanner, long reach socket or a box spanner, or really should just cut down the stud a bit. Be careful using anything powered or you could crack the toilet. It only needs to be hand tight with a spanner or short socket wrench.

    I doubt it's that bolt which is the problem. The mounting screws that hold the hinge fittings to the seat itself are intended to allow a seat to be fitted to toilets with different bolt spacings, but frequently work loose.

    A big gob of clear silicone helps stop small movements, which become large ones

    A Crescent X6 ratchet wrench set is designed for just such an application as this - the ratchet bits and ratchet handle have a hole through the middle to accommodate long threads. Available from amazon

    Have you fitted the nylon sleeves and rubber domed washers to the fitting?
    These help to prevent movement when someone sits down. Run the nuts up finger tight and then gently tighten until very little movement is detected.
    Check tightness once a month to 6 weeks.
