What are the main advantages and disadvantages of precision screws

Precision screw is a kind of high-precision fastener, which is widely used in automobile, aviation, electronics, optics, instrumentation and other fields. Its main advantages and disadvantages are as follows: Advantages: 1. High precision: Precision screws are machined with high-precision machinery, with very precise diameters and lengths, which can ensure the quality and stability of fasteners. 2. Strong wear resistance: Precision screws are usually made of high-strength materials with strong wear resistance and corrosion resistance, which can ensure the service life of fasteners. 3. Safe and reliable: The design and manufacturing of precision screws comply with international standards, with good safety and reliability, and are suitable for various high-precision and high safety requirements occasions. Disadvantages: 1. High cost: The manufacturing process of precision screws is relatively complex, requiring high-precision processing equipment and precision testing instruments, resulting in relatively high costs. 2. Easy to be damaged: Due to the high precision of precision screws, their structure is relatively fragile and easily damaged during use. 3. Long production cycle: Precision screws require a very strict manufacturing process and testing process, so their production cycle is relatively long and may have a certain impact on production efficiency.
