Sweet guitar! But a rule of thumb for you.

When tightening a locking nut, just tighten to the point where you cannot move it without applying pressure. Basically, when your thumb feels it stop, don't force it further, that will strip your nut. Finger tight is enough to keep tuning stable.

McMaster-Carr is an unbelievable resource for basically everything but especially esoteric sizes and shapes of bolts, screws, nails, etc.
