    If it's not too badly bent, it'll probably do to straighten it out and run a die down it.
    Have a hunt around for a local machine shop, at worst they'll be able to make a new one.

    Just to say it's not a metric thread so find out the thread size first.

    Being of American manufacture the thread will be Imperial.

    My 'The Rock' has 3/8" UNF (Unified Fine) threads, but it's an older one with black screws, not the the bright steel ones shown in the link.

    My 'Rock BR' has the bright steel screws, and they're threaded 3/8" UNC (Unified Coarse).

    The UNC has 16 TPI (Threads Per Inch), and the UNF one has 24, if you want to hold it up to a ruler.

    Any machinist will easily identify the thread anyway.

    He might tap out the hole with a 10mm tap and stick that in either. We used to do that on old Lucas starter motors and it worked. You will have 1 disimilar bolt though, get it in same colour and it will be fine.

    There should be no need though.
    Unless the screw is totally borked beyond redemption, it should be very possible to just straighten it and tidy it up with a die; otherwise UNF/UNC stuff is readily available off the shelf and it'd the only be a matter of turning a point onto the tip.

    i toke the screw out today to see how much it was bent and to my amazement it was straight as an arrow......tried it in the other two legs and had no problem but when i try to put any of the three screws into the front leg they get as far as the point just comin out of the bottom of rest. so i investagated the rest more and there was no visable fault so screwed it in from the bottom of the rest it was very hard to get it all the way throught but got there. then i repeated this a few times and tried it from the top and it now works fine crisis averted..... thanks for all your suggestions
