What are the Main Components of Screws from China?
Screws have three main components which you will use for different screw purposes.
Here are the three main parts of the screw you should know about.
Parts of screw
Head of the Screw
The head is the upper part of the screws which can be countersunk, rounded or raised.
It also has different types of slots that can accommodate different types of screwdrivers.
You can have a different type of shapes such as hex, tox, Philips, or square heads.
You will also see the screw shank just below the head which connects the head and the lower part.
In other words, it is the middle part of the screw that is often smooth in nature.
Threads or Spirals
You will also see the spirals or threads on the bottom part of the screw which drives into the device.
It has threads or spirals or teeth which increase the hold on the devices thus making them stronger.

How do you Measure Screws from China?
There are different methods that you can use to measure the screws.
Here are the main methods that you can use in measuring the screws.
- Screw Gauge which involves measuring the outer diameter of the screws
- Shaft length involves measuring of the part of the screw to drive into the surface
- Thread per inch (TPI) involves measuring the number of threads per inch on the screws.
What are the Properties of Screws from China?
When looking for a screw, you must also consider looking at the properties of the screws.
In this case, you will look at three particular properties which include:
When looking at the mechanical properties of the screws, you will look at tensile strength, Vickers hardness and Brinell hardness.
Apart from that, you will also look at the Rockwell hardness, surface hardness, yield strength, and elongation after a fracture.
Physical properties of screws are more or less similar to the mechanical properties of screws.
In this case, you will focus on the hardness of the materials that you will use to make the screws.
Here, you will look at how good the screws are at conducting an electric current.
This will depend greatly on the type of materials that you use in manufacturing screws.
