What material is used on the anti-loosening screws?
One is to attach the engineering plastic to the surface of the screw with special engineering plastics and special processing techniques, so that the engineering plastic generates a strong counterforce during the locking process, increases the friction between the screw teeth, and provides insulation. The vibration resistance is correct, completely solving the problem of loose screws.
Another type is anti-loosening screw adhesive, anti-loosening screw pre-coated adhesive, and anti-loosening adhesive. It is a high-viscosity, non-toxic, thixotropic, water-based pre-coated thread sealant, suitable for automatic gluing. After drying, the product becomes an elastic, highly adhesive, and non-curing sealant, which can be used for conical or linear sealing.
Anti-loosening screws do not require adhesives.
One of the existing methods for preventing loosening of screws is to apply adhesive to the common threaded parts (screws) and female threaded parts (screws). However, at this time, the screw is in a bonded state, so the part used to rotate the screw (the cross hole) is prone to damage when removing the screw, resulting in a significant increase in the cost of fastening.
Therefore, the new screw has innovated in the thread shape of the common thread component. Specifically, the thread shape of the common thread component is also relatively stable, causing the threads of the common thread component to interfere with each other, thereby playing a stable anti-loosening role. In addition, it also has the following characteristics:
(1) By using special screws to interfere with the ventral surface of the teeth with stable shapes, the degree of squeezing and cutting when the screws are screwed in can be reduced, which can prevent chips.
(2) The top of the thread is flatter than that of a common small screw, so the female thread part has better insertability when tightened.
The new product can be manufactured using the same production process as ordinary screws, and its cost is much lower than that of anti-loosening measures such as adhesives. The screw sizes (diameters) are 1.4mm, 1.7mm and 2.0mm. The material is carbon steel. Various gold plating treatments can be carried out.
