Difference between Concrete nails and Concrete Screws
Both concrete nails and concrete screws are made of carbon steel.
Not like other kinds of nails, concrete nail passes through an additional process: heat treatment. It’s more tenacious and stronger than the concrete screw.
The concrete nail has a round flat head and a smooth shaft, or a straight fluted/ twilled fluted shaft. Like other nails, the concrete nail has a diamond-shaped point.
Compared with concrete nails, concrete screws have tighter spirals on the shaft in order to dig into the concrete. This spiral also give it holding power when driven into the concrete.
The concrete screw is also a self-tapping screw.
Concrete nails are often used to join wood with concrete surfaces, for example, basement construction, etc. Generally speaking, the concrete nails can be used for lumber plate and concrete fastening.
However, it’s worth mentioning that the concrete nails can’t be used to hang things like selves or frames, for its shaft might bend and slide out of the hole easily.
Concrete screws are used for the fastening of medium-high load applications with concrete, brick or stone surfaces.
Unlike the concrete nail, this can be used to hang shelves, brackets, or frames on the brick surface.
