A witty expression based on hardware: two nuts alone can’t fasten anything without a bolt. Used metaphorically to suggest that just having more of the same doesn’t complete the
job — sometimes what’s needed is a complementary part, not another identical
one.
Literal meaning: In mechanics, two nuts can’t do the job of a bolt; a bolt holds things together, while nuts secure it in place. Without the bolt, the nuts are useless.
Figurative meaning: Two
people with the same flaws, mindsets, or roles often can’t make things work. Balance and contrast matter.
