This is a spreader attachment to the mast. If the screws are Phillips or Robertson heads use the centres to drill the ss scree out get a real good bit. You’re gonna have to clean up the treads with a tap so might as well drill a little bigger to get fresh metal then tap to a bigger fastener. Not that hard and you can then use gobs of anti seize when you reinstall won’t matter the next owner 30 years latter will have to deal with what you’re dealing with now
