Non standard anti loosening screws
Screw is the general term for fasteners, commonly used in everyday language. Screws are essential industrial necessities in daily life, such as cameras Glasses clocks and watches. Extremely small screws are used for electronics, etc; Television Electrical products Musical Instruments. Furniture and other general screws; For engineering Architecture. The bridge adopts large screws Nut; Transportation equipment Airplane tram. Use the car together with other screws. Screws play an important role in industry, and as long as there is industry on Earth, the function of screws is always crucial.
Loose screws have always been a serious problem in industrial manufacturing and industrial products, even a fatal hazard. Such occasional safety accidents have occurred in our daily lives Work and even transportation The national defense and military have caused unpredictable harm. Therefore, engineers from various countries Scientists have been deeply studying screw fastening for a long time, praying for a final solution.
Hezhong loose screw "is a special technology that permanently attaches special engineering plastic to the thread, so that during the locking process of the internal and external threads, the engineering plastic is squeezed and generates a strong recoil force, greatly increasing the friction between the internal and external threads and bringing absolute resistance to vibration. Hezhong loose screw provides this resistance completely distributed throughout the entire tooth engagement section of the internal and external threads, and this friction force is independent of the locking pressure between the internal and external threads. Once the Hezhong loose screw is locked in, the friction force is immediately generated and permanently exists. Even if the tight and resistant screw cannot be locked, it will not loosen. Unlike previous anti loosening methods, it relies on the frictional force caused by the pressure after the screw is locked to initiate the retreat effect. The screw becomes slightly loose, the pressure decreases, and the frictional force quickly disappears, losing its stopping effect and causing the screw to loosen.
Due to the strong elasticity and memory of this special engineering plastic on HeZhongSong screws, the accuracy of HeZhongSong screws can be disassembled 5 to 50 times, and the fastening function of HeZhongSong screws still exists for a long time. Because this type of fastening engineering plastic is environmentally friendly light. Repeatably detachable, it has become a reliable solid anti loosening screw product today. In addition, the special engineering resin on solid anti loosening screws has high chemical stability and acid and alkali resistance Other solvents will not oxidize or corrode metals, so solid anti loosening screws will not rust The phenomenon of electroplating detachment contributes to the lightweight, weather resistance, and high-quality requirements of products.
This special engineering plastic, commonly known as non-standard anti loosening adhesive, is suitable for various shapes Bolts and nuts made of various metal materials are used for fastening treatment. The fastening screw is called Hezhongsong screw, which is suitable for tightening moving parts. Hezhongsong screws were first used in space shuttles and later promoted to the automotive manufacturing industry in Beautiful Country. With the maturity of manufacturing technology and the reduction of costs, Hezhongsong screws are widely used in 3C Bicycle Skating equipment Furniture Sports equipment The medical device and other industries have completely replaced traditional check washers, fully demonstrating the reliability of HeZhongSong screws.

Screw tightening principle:
Pre set torque non-standard anti loosening screw "- also known as" Hezhong loosening screw ". It is a special engineering plastic processed on the screw, which generates strong friction torque and back impact during the locking process due to the compression of the engineering plastic, resulting in full tooth contact and providing absolute vibration resistance, making the general screw a permanent strength non-standard anti loosening screw, completely solving the problem of screw loosening.
The necessity of tightening screws:
The screws/nuts used in the industry mostly belong to the JIS secondary tooth specification, which has a tolerance of more than 20 screw diameters and 2B inner diameters of nuts. Therefore, when screws/nuts are combined with locking products, there will be gaps and they cannot fit tightly. When the product vibrates In operation and impact situations, the locking force is easily lost, and there is a risk of screw loosening!
Technology application industry:
Like a camera Glasses clocks and watches. Used for tightening extremely small screws in electronics, etc;
Like television Electrical products Musical Instruments. General screw fastening treatment for furniture, etc;
Like engineering Architecture. The bridge Amusement equipment is used for amusement equipment Nut tightening treatment;
Like a means of transportation Airplane tram. Cars and other vehicles are fastened with screws of different sizes.
Screw fastening plays an important role in industry, and as long as there is industry on Earth, the function of screw fastening is always crucial.
