Hi all,
I'm trying to remove some screws from a boiler superheater in order to replace a gasket but they are stuck solid and have now partly snapped at the heads. Can anyone please offer any help?
I've tried heating them then using pliers but there isn't enough to hold on to, I'm not sure of the thread size but they are only perhaps about M3 and from what I can see stud extractors dont seem to go that small. I did wonder if it is worth trying to silver solder something onto the broken end to give something to grip.
Many thanks and a Happy Christmas to all
