Cool. None of my enclosures even have screws. Never had a "leak" or anything break apart. Odd.
80 amp, and not blowing the fuse. You are no where near, peak power. Not even half. Sooooo, your good. No breaking shit,.. from power anyway.
Edit- maybe just a really poorly built enclosure. I've never, in my decades of audio, had the privilege of seeing anyone "blow" their box apart,, unless it was a pile of wood just hucked together, or a prefab. Even then, it wasnt from "power". But good luck to your goal mate.
