    There one size fits all, they aren’t standard screws either they have a tapered edge

    is it hollow ??
    if so it needs a different attack method
    if solid but composite then try say red plugs knocked in first

    Yes Hollow

    The fittings are placed between two boards with a gap in between for the fastener linked above.

    it’s a small opening to get anything in like a dowel or toothpicks as I can’t trim them with the space available

    we need the joist it goes into and grips rather than what it is securing thanks
    a 6mm screw hole is very big so you need the biggest plug probably a yellow or red to try and get stuck in the top surface off the joist and get it to grip a brown would be perfect [a 5.5-6.5mm hole]but may struggle to knock it through
    pumping in all sorts off carp will probably fail as you need it to solidify in the area around the screw hole to give grip
    as an aside what is under the joist ??

    Ground under the joist, it’s suspended of the floor a couple of feet

    what is the actual profile off the joist??
    if you insert a screw into one off those "T" clamp bits what sticks out is it all thread and no shaft ??

    perhaps a longer screw to stick through the bottom assuming the base is thick enough and wont just split??

    Not sure that will work

    I’ll try wood filler again today, as it worked on a few other holes yday, just this one had too many to screw back into.

    if not I’ll get someone to replace that section
