Stainless Steel Screws

10-21

Stainless steel screws are made of metal, and metal corrosion prevention methods are mainly four aspects, namely, the nature of the material itself, the use of the environment, the interface between the material and the environment and improve the design of metal structure, if the use of complete corrosion-resistant alloy to manufacture stainless steel screws, unless there is a special need, otherwise, in terms of the economic concept is not cost-effective, the appearance of the screw with the environmental elements that generate corrosion is completely isolated from the impractical. Improve the design of metal structure can be in a certain situation to improve the impact of special circumstances, but most stainless steel screw design can not be fully amended, and its maintenance role is not permanent, so this method can not basically deal with the problem, as long as the surface corrosion prevention, that is, the appearance of corrosion prevention treatment is the most widely used approach.
Stainless steel screw exterior corrosion protection treatment is the use of various methods to apply maintenance layer on the metal exterior, the role of the metal and the corrosive environment isolation, in order to inhibit the generation of corrosion processes, or reduce the corrosive media and metal exterior contact, so as to avoid or reduce the purpose of corrosion.
The main purpose is to make the industrial products composed of fixed one, in use often occur between the teeth and teeth can not be close, too hard to lock the screw head broken away, or poor locking teeth pattern and failed to achieve the conditions of use, are precision problems. Screws are ""quantity products"", not handmade works of art, 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 screw is usually 6g level (level 2, ""IFI"" for 2A teeth), and the rough screw for construction work is 8g level (level 3, ""IFI"" for 1A teeth).

Screws are tools that use the physics and mathematics of the beveled circular rotation of an object and friction to tighten the instrumental mechanism in a stepwise manner. Screw is the generic term for fastener, the everyday verbal term. Screws are indispensable industrial necessities in daily life: such as cameras, glasses, clocks and watches, electronics, etc. use of very small screws; TV, electrical products, musical instruments, furniture and other general screws; as for engineering, construction, bridges use large screws, nuts; transportation apparatus, aircraft, trams, cars, etc. are used for the size of screws and. Screws in industry has an important task, as long as the existence of industry on earth, the function of screws will always be important. The screw is a common invention in the production life of people for thousands of years, according to the application area, it is the first human invention.
The function of the screw is mainly to join two workpieces together and to act as a fastener.
