they don't really make locking nuts for bass i don't think, but locking bass keys are certainly a thing.
softer nuts can indeed wear, but on fenders with their shallow headstock string angles it's not a big problem, especially if the slots aren't cut super-low.
some materials may sand easily but still not wear so fast.
