Morphology

tough + as + nails

The phrase uses the common simile pattern 'as X as Y' and relies on the literal property of 'nails' (hard/durable) to amplify 'tough', so the meaning 'very strong/resilient' is directly inferable from the constituents. This comparative/metaphorical logic is cross-linguistically common, so a B1 learner who knows the words will most likely understand the MWE.

Etymology

The idiom tough as nails compares a person to the hard metal nails used in building. Nails are very hard and hold things together, so saying someone is tough as nails means they are 'very strong' and not easily hurt or upset.
