Metal Screw SS201 304 Plain Polished Hexagon Head Drilling Screws With Collar DIN7504(K)
1,Description:
The tail of the screw is generally shown as the shape of drilling tail, the hardness of this screw is very strong, compared with ordinary screws, not only the ability to maintain better, the effect of connecting the object is very firm, for this performance of the screw, generally do not need auxiliary processing, you can directly drill a hole on the object directly to lock the object, not only very convenient to use, It can also greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of staff in various fields.
Screws are indispensable in daily life and industrial manufacturing, so screws are also known as industrial rice. The application range of screws is: electronic products, mechanical products, digital products, power equipment, mechanical and electrical machinery products. Screws are also used in ships, vehicles, water conservancy projects, and even chemical experiments.
Screw types, whether it is very small screws for glasses or large screws for large heavy electrical engineering. The accuracy of the screws is usually 6g class (2, the US specification "IFI" is 2A teeth), and the rough screws used in construction projects are 1g class. Screws are widely used, so the screw market is large, resulting in more manufacturers producing screws. When choosing a professional screw manufacturer, buyers need to understand some professional basic knowledge of screws, such as screw classification standards and American screw specifications.
| Applications |
| car | In high-strength applications such as automotive engines, heavy-duty machinery, and bridge construction, they are preferred for their larger support area and better anti-loosening performance. |
| mechanical | Mechanical, electronic, automotive, construction and other fields, used to connect various mechanical parts, circuit boards, engines, transmissions, building structures, etc |
| energy | For the energy industry, brackets and fixtures used to connect power generation equipment and transmission lines
|
| architectural | In the field of construction engineering, shipbuilding, and petrochemical industry, it is used to connect building structures, improve the navigation safety and stability of ships, and ensure the safety and stability of petrochemical equipment |
The main purpose is to make industrial products composed of a fixed body, in the use of teeth and teeth often can not be close, too hard to lock the screw head is broken, or poor dental lock is not tight and failed to meet the conditions of use, are precision problems. Screws are "quantity products", not hand-made artworks, in mass production, in order to achieve high precision and stable quality and popular price supply to consumers for the purpose. The accuracy of the screws is usually 6g (Class 2, the US specification "IFI" is 2A teeth), and the rough screws used in construction projects are 8g (Class 3, "IFI" is 1A teeth).
3,Specifications:
| material |
| aluminium | Aluminum has excellent thermal and electrical conductivity. However, aluminum is naturally soft and may produce gelatinous buildup after processing. If not properly operated, it is difficult to cut during processing. |
| titanium | Edm machining is well suited for titanium because the process can withstand the viscosity of this alloy and break down lengthy chips. However, deionized water is needed as a medium to help control the heat generated during processing.
|
| steel | Steel is a very strong metal, and many manufacturers tend to use wire cutting machines instead of CNC machines for machining complex steel features. However, this material generates a lot of heat, so necessary precautions need to be taken. |
| brass | Brass has a high tensile strength and is easy to cut by machine. But the cutting speed should be slow because it is a soft metal. |
4,Feature Advantage:
Stainless steel screws are made of metal, and metal corrosion prevention methods mainly have four aspects, that is, the nature of the material itself, the use of the environment, the interface of data and the environment and the improvement of metal structure design, if the use of complete corrosion resistant alloy to manufacture stainless steel screws, unless there are special needs, otherwise in the economic concept is not cost-effective, It is also impractical to completely isolate the external surface of the screw from corrosive environmental elements. Improved metal structure design can improve the impact of special circumstances in a certain situation, but the design of most stainless steel screws can not be fully corrected, and its maintenance role is not permanent, so this method can not deal with the basic problem, as long as the surface corrosion prevention, that is, the appearance of corrosion prevention treatment is the most widely used method.
Stainless steel screw surface corrosion prevention treatment refers to the use of various methods to apply a maintenance layer on the metal surface, its role is to isolate the metal and the corrosive environment, to inhibit the corrosion process, or reduce the corrosive medium and the metal surface contact, so as to avoid or reduce the purpose of corrosion.
