    Default Parallel port thread

    OK it's cold and dark here and the path down to the workshop is haunted so not going out to get my calipers and screw gauges.

    On the parallel port you have these little retaining screws that the cable screws into, any idea what thread it is as I have to make a couple of new ones about 5/8" long to take a gender changer.

    I've just checked one,and it looks to me like it's #4x40 UNC.You could probably rob the screw of an old printer connector or similar.They seem to have fairly long screws.

    I think the male standoffs are 6-32 UNC, and I believe the the thumbscrews that are normally attached to the plug and screw into these are 4-40 UNC John.
    Not positive, but I seem to remember checking this out a couple of years ago.

    By the way John, it's the same screw that's on an RS-232 shell. Sow you can steal the screws off an old serial connector...

    Having a several Spanish biker friends I can say with some insider knowledge that it isn't !!!
    BTW Spanish swearing tends to concentrate on milk, faeces, mothers, sisters, The Virgin Mary & God in some interesting combinations.

    Oh yes - the original question - 5BA looks pretty close.

    The standoffs are metric 3.5 x .8 that is so close to 6-32 that it doesn't matter . The thumb screw thread is 4-40.
