The knowledge about precision screws

What is a precision screw? In fact, they are the micro screws that everyone usually refers to. They are generally used in electronic appliances, mechanical equipment, home appliances and furniture. Today, the editor will give you a good introduction to it.

1. Mainly divided into two categories

Precision screws are mainly divided into self-tapping screws and machine screws. The two types have very obvious differences. The tail of the self-tapping screws is pointed, and the shape of the head is various, such as pan head screws, countersunk head screws, semi-sunk head screws, etc. Of course, the self-tapping category also includes many subdivided categories, such as cutting tail self-tapping screws, countersunk head self-tapping screws, self-tapping screws, etc. The tail of the machine screws is not pointed, and the thread is relatively uniform.
The common ones are carbon steel and stainless steel. The former is made of iron, and is divided into low, medium and high carbon steel in terms of material; the latter is made of stainless steel, and its has many kind of stainless steel types. I will not list them all here

3. Related process

There are many precision screws that need to be electroplated, generally referring to steel, and some customers also require electroplating of stainless steel. The plating color is also available in environmental protection and non-environmental protection. There are also many customers who have higher requirements for the hardness of the screws, and they need to be hardened. If some screws are not hardened, they will slip or break when applied to related products, which will affect the normal use of the product. Therefore, hardening is necessary in many cases.
