Looking at the pic I agree the best plan might be to simply leave the existing axle adjustment screwand find a replacement on the other side. The mudguard screw should submit to a pair of {good} molegrips and a well fitting screwdriver used together. The moles on the screw head at right angles to the twist and the screwdriver used in conjunctionwith them in a back and forth movement.
Just out of interest what leads you to believe the frame is 531 ?
It looks quite basic and [I hope I'm wrong] but I've noticed a few frames appearing with 531 labels on them But a double butted 531 frame was [as you know] always quite a catch. Anyhow, as I said I hope I'm wrong. Good luck with the bolts.
