Ah ####, that's rough man =\, yea not sure why someone recommend a brass screw ? They're definitely more fragile than a steel one, I've broken brass punches accidentally with just a little inappropriate force and that scares me to use a load bearing screw made of brass =\ You gotta get that one out somehow to replace it.. maybe try and drill it out? Or drill a small hole into it and try to get a screw driver into the malleable brass and unscrew it ? Goodluck man
Lol they are only more fragile when you apply force to it. They have give to them but not meant to be torqued the fvck out of... duh
