Like a nail, the screw is (usually)
Small piece hardware used to fix the material together.
One of the main differences is that the design of the screw is able to easily remove and replace without damaging the screw itself or the material it connects.
Most screws are made of some kind of metal, and many of them are covered with a rust-proof coating.
In addition to the material, the screws vary in the shape of the head, the type of head, the thread and the purpose.
The machine screws are designed to hold the mechanical parts together.
Most machine screws require that they have been drilled and threaded, although there are several types of machine screws that are capable of self-tapping holes.
Like other screws, the machine screws have various shapes and sizes.
The head machine screw is the machine screw, the top of the head is flat, and the side is round.
They are similar to oval head machine screws and also have round sides;
The difference is that the top of the Oval screws is also round compared to the flat screws, and they have a tapered base.
Both are commonly used in metal applications.
The disc head machine screws can also be distinguished from the flat head screws, which also have flat head screws.
However, the flat head screws are tapered on the lower side of the head, so they can be flush with the material being driven.
At the same time, the bottom of the round head screw is flat and the head is round, much like half a sphere.
The round head screw cannot be placed flush with the driven material;
On the contrary, their heads stick out like pimples.
The screw of the disc head machine can also be designed into multiple head types.
