Dreaming of nuts and bolts could symbolize wisdom.

Positive: Dreaming of nuts and bolts could represent the bottom line of an issue. It could also mean indispensable wisdom. They could also symbolize to lock or fasten something or something that is secure, immovable, or unyielding.

Negative: Seeing nuts and bolts in your dream that are loose or rusty may represent a weak foundation in your life.

(Proverbs 4:7).
