Yes. A steel nail has a Mohs hardness greater than that of fluorite.
Halite has a hardness of 2.5 on the Mohs scale, while a fingernail has a hardness of about 2.5 as well. Therefore, halite can be scratched by a nail.
If a mineral can be scratched by a streak plate but not by a masonry nail, it indicates that the mineral has a hardness less than that of the streak plate but greater than that of the masonry nail. The Mohs hardness scale helps to categorize minerals based on their scratch resistance, with the streak plate typically having a hardness of about 6. The masonry nail, being softer, has a hardness lower than 6, allowing the mineral to resist scratching by it.
It is about 2.5 in the Mohs Hardness Scale.
The hardness of a steel nail is about 4.5 (About the same hardness of the mineral Fluorite.)
Scratching a mineral with a nail is a test of hardness. It helps determine the relative hardness of the mineral compared to known substances on the Mohs scale of mineral hardness.
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5

A steel nail cannot scratch minerals that are harder than itself, which has a Mohs hardness of about 4.5. This means it cannot scratch minerals such as quartz (hardness 7), topaz (hardness 8), corundum (hardness 9), and diamond (hardness 10). These minerals possess greater hardness and will resist scratching by a steel nail.

hardness
Mineral hardness is tested on a glass plate or usually a finger nail.
Scratching a mineral with a nail is a test of hardness. The Mohs scale of mineral hardness ranks minerals from 1 (softest) to 10 (hardest), with talc being the softest and diamond being the hardest. If a mineral can be scratched by a nail (with a hardness of around 2.5), it would be classified as having a hardness lower than 2.5 on the Mohs scale.
