Advantages and disadvantages of plastic screws

Advantages and disadvantages of plastic screws
1. Compared with ordinary metal screws, the biggest advantage of plastic screws is that they have good insulation properties and are not conductive.
2. In addition, because of non-metal manufacturing, there will be no signal interference such as eddy current under the influence of current or other electrical signals, and its anti-interference is somewhat suitable for communications and other industries.
3. Plastic screws have better acid and alkali resistance. Among them, the best PVDF screw is polypropylene. Both have strong acid and alkali resistance. Compared with the former two, nylon screws are resistant to strong acids and alkalis. The performance is relatively poor, so in some strong acid and alkali environments in the electroplating industry, plastic screws, especially PVDF screws, have a wide range of applications
defect:
1. The biggest disadvantage of plastic screws is that the torque and strength of ordinary plastic screws are not as good as ordinary metal screws. If the torque is too large, there is a possibility of slippage or head fracture.
2. Due to the shrinkage of different plastics, changes in temperature and humidity, and the length of the molding cycle, the size error of the plastic screws is tolerable. Dongguan Plastic Screw Factory will introduce to you. In addition, because the material of ordinary plastic is relatively soft, the conventional ring gauge measurement method cannot be used.

How to distinguish between high-strength nuts and ordinary nuts?

What is the difference between high-strength nuts and general nuts, in fact, you only need to understand their standards and other characteristics to easily distinguish them. The so-called high-strength nut is a special bolt with high strength and high fatigue resistance used in special equipment or engineering. Of course, generally high-strength nuts are used with high-strength bolts to achieve better application. We generally see that many bolts with M heads in the market are ordinary nuts, not high-strength nuts. The calibration side of the general hexagonal head nut is the following pattern M30, and M30 indicates the thread standard, that is, the inner diameter of the thread is 30mm. Grade 10 indicates the functional grade of the bolt, and tZn is the surface treatment method. Other types of bolts also have their own expressions, but generally threaded bolts have to use the original functional grade of "M": The functional level of the nut is divided into 3, 4, 4, 5, 5.8, 6...

Anti-corrosion method of stainless steel screw

Stainless steel screws are made of metal, and there are four main methods for metal corrosion protection, namely the nature of the material itself, the environment in which it is used, the interface between the material and the environment, and the design of improving the metal structure. If a complete corrosion-resistant alloy is used to manufacture stainless steel screws Unless there is a special requirement, it is not realistic in terms of economic concept, or the appearance of the screw is completely isolated from the environmental elements that will cause corrosion, which may not be feasible in practice, and it may be very difficult. Improved metal structure design can improve the impact of special circumstances under certain conditions, but the design of most stainless steel screws cannot be fully modified, and its maintenance function is not permanent. Therefore, this method cannot basically deal with the problem, as long as the interface is Anti-corrosion, that is, surface anti...
