Golden Age Audio R1-SM Ribbon Mic Shock Mount

the thumb screw for the shock mt broke after the 4th time it tried to tighten the shock mt normal hand tightening wont hold the ga r1 mic it kept drooping so when i went to tighten it the thumb wing screw broke i replaced it with an 5 mm allen head screw and it works perfect but that seems to be a weak point to it..
