White square drive counter sunk RV screws needed

I have some screws in my Lance TC that don't tighten up properly and I would like to replace them with longer and maybe larger diameter screws. I cannot find any that are larger then #8 and none of them are the flat head, counter sunk screw like are now in there. I tried an internet search and have tried the McMaster-Carr website with no luck.

Anyone found a source for these?

Thanks!

    What type of thread or type of screw?
    Deck screws come larger with Robertson heads

    Nobody in the US will know that screw as a "Robertson" head. the term used here is an internal square drive head. the tools are common. Less so the screws.

    I find the easiest way to get these is to go to a smaller RV repair shop and buy some off of the guy. I have been to numerous Fastenal, Tacoma Screw and others and have yet to find them. But they can be ordered from RV parts suppliers by the hundreds.

    I often use in replacement a star drive screw if it is not on the outside of the body.

    As a last resort you might try to order them from McMaster-Carr.

    Yup. Canadian Peter Robertson invented that in 1908 .
