The invention of plastic can be called a masterpiece of mankind in the 20th century, and it has undoubtedly become an indispensable raw material for modern civilized society. As a member of the plastic family, nylon has revolutionized human life.

Chinese name

Nylon screw

Foreign name

plastic screws

Also known as

Plastic screws, PC screws, PVDF screws, etc.

Material

Nylon 66 (NYLON66), etc.

Nylon screws (plastic screws), also known as plastic screws, nylon screws commonly used in China are mostly made of nylon 66 (NYLON66), also known as plastic screws.

Since the large-scale application of plastic products in industry and daily life in the 1970s, plastic products have become a relatively important branch of the petrochemical industry and have been used in many application fields. Compared to traditional metal screws,

By material

Nylon screws, PC screws, PVDF screws, PP screws, etc.

Divided by screw head type

According to the shape of the head, it can be divided into: pan head nylon screw, countersunk head nylon screw, outer hexagon nylon screw, inner hexagon nylon screw, nylon set screw, etc.

According to the shape of the slot, it can be divided into: cross, slotted (slotted), hexagon, rice, plum, etc.

Divided by screw specifications

Metric thread M2, M2.5, M3, M4, M5, M6, M8, M10, M12

American screw teeth 2-56, 4-40, 6-32, 8-32, 10-32

According to the above classification, many different types of nylon screws can be combined.

1. Compared with ordinary metal screws, the biggest advantage of nylon 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. Its anti-interference advantage is suitable for communication and other industries. 3. Nylon screws have better resistance to acids and alkalis. The best PVDF screws are followed by polypropylene. Both have strong resistance to acids and alkalis. Plastic screws are more resistant to acids and alkalis than the previous two. The performance is relatively poor, so in the strong acid and alkali environment of some electroplating industries, nylon screws, especially PVDF screws, are widely used.

1. The biggest defect of nylon screws is that the torque and strength of ordinary nylon screws are not as good as ordinary metal screws. Excessive torque may cause sliding teeth or head breakage.

2. Due to the shrinkage of different plastics, temperature and humidity changes, and the length of the molding cycle, the dimensional error of nylon screws is allowed to be large. In addition, due to the softness of ordinary nylon, conventional ring gauge measurement methods cannot be used.

Nylon "loves" water absorption. Under different temperature and humidity, nylon products will absorb water to reach a certain percentage of its own content is to stop water absorption, the so-called "balance point". The water absorption ratio of the equilibrium point will change with its surrounding environment (temperature, humidity, etc.).
The speed at which nylon absorbs water is also related to the wall thickness of the product.
The control of the water absorption of nylon has a great impact on the actual application of the product. The amount of water absorption is very important for the performance of nylon products.
-To get higher tensile strength, the water absorption ratio should be small.-To get better toughness, the water absorption ratio should be higher. How does the water absorption ratio affect the performance of nylon products:
-High water absorption will affect products with:
Better endurance (anti-fatigue), better toughness, better elongation-high water absorption ratio will also affect the product:
Reduced tensile strength, reduced electrical insulation, and reduced dimensional stability

Nylon screws have high-quality properties such as insulation, non-magnetic, corrosion resistance, beautiful appearance, and never rust. Modified engineering plastics have comparable strength and impact resistance to metals. We often say that nylon screws are commonly called RENY After 30% glass fiber, its mechanical properties are far superior to ordinary nylon. The materials used for nylon screws are increasingly diversified, their performance is continuously improved, and their application fields are becoming wider and wider.
1. Medical equipment industry (insulation, non-magnetic, environmental protection, anti-interference, making medical machinery and equipment safer to use)
2. Wind power industry (Isolation and insulation of chassis circuit PCB board)
3. Aerospace industry (insulation, anti-interference number on electronic equipment)
4. Office equipment industry (never rust, beautiful and practical)
5. Petrochemical industry (high temperature resistance, chemical resistance, corrosion resistance, extended equipment life)
6. Electronics industry (insulation, anti-interference, light weight)
7. Communication industry (insulation, non-magnetic, safety)
8. Shipbuilding industry (acid, alkali, corrosion resistance, extended service life), etc ...
The specifications and sizes of nylon screws meet the requirements of different occasions.
