Screw performance

Self-tapping screw
For self-tapping screws with a diameter of 0.8mm to 12mm. Generally, these screws are of high hardness. Self-tapping screws should undergo screw-in test, that is, screws should be screwed into a test plate to check whether the hardness of screws meets the standard,
Drill tail screw
The tail of a screw is usually in the shape of a drill tail. The hardness of this screw is very strong. Compared with ordinary screws, it not only has a good maintenance ability, but also has a very solid effect in connecting objects. For screws with this performance, it is generally not necessary for auxiliary processing. You can directly drill a hole on the object to lock the object, which is not only very convenient to use, but also can greatly improve the efficiency of work. This kind of drilling screw is the first choice of the staff in various fields.
Anti-corrosion technology
Stainless steel screws are made of metal, and there are four main ways to prevent metal corrosion, that is, the nature of the material itself, the environment used, the interface between the data and the environment, and the improvement of the metal structure design. If stainless steel screws are made of a complete corrosion-resistant alloy, unless there is a special requirement, it is not cost-effective in terms of economic concepts, and it is also impractical to completely isolate the appearance of the screw from the environmental factors that cause corrosion. Improving the design of metal structure can improve the impact of special circumstances under certain conditions, but the design of most stainless steel screws can not be fully corrected, and its maintenance function is not eternal, so this method can not basically deal with the problem, as long as the surface anti-corrosion, that is, the surface anti-corrosion treatment is the most widely used method.
Anti-corrosion treatment on the surface of stainless steel screws refers to the application of various methods to apply a maintenance layer on the surface of the metal. Its function is to isolate the metal from the corrosive environment to inhibit the corrosion process, or reduce the contact between the corrosive medium and the metal surface, so as to achieve the purpose of avoiding or reducing corrosion.
