    I would thought they would be standard, if they are all different i will do the hardware store trick
    Thanks

    I doubt they are a standard size as there are multiple manufacturers of the squid screens. The largest I would think is 1/4-20 but could be one of the smaller sizes on this chart, such as #12 or #10. Do you have a hardware store you can pick up a few different sizes (and threads) ?

    I’d go pull mine and verify the size but I wouldn’t take it to the bank that they are all the same…..

    Not sure what I am missing, but no picture and not clue what you are referring to………………………Is this and “engine thing”, or a “boat thing”? One has typically nothing to do with the other..
