a nail designed to penetrate concrete and hold
Concrete- I remember when concrete nails were made of a forged tungsten steel.
that is a hard one. You will probly need a hole in the concrete with a drill or something. Or dynimite.
Any sort of post that you are going to be attaching to concrete needs to be securely fastened to the concrete using nuts and bolts. Liquid nails is a strong product but does not give assurance that the posts will be securely fastened to the concrete.
No, you cannot use a staple gun on concrete. Staple guns are designed for use on softer materials like wood or fabric, and they do not have the power to penetrate concrete. To fasten materials to concrete, you would typically use a concrete nail gun or a hammer drill with concrete screws or anchors. These tools are specifically designed to penetrate and secure items to concrete surfaces.

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.

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.
