hairline crack
Barely visible split
A hairline crack is a very fine, narrow fracture—thin as a strand of hair—in a hard surface like bone, concrete, or plaster.
The crack may be barely visible but can signal structural weakness: The inspector found hairline cracks in the foundation.
In medicine, a hairline fracture is a stress injury to bone that doesn't fully break it.
