The service life of bolts and nuts is related to a number of factors, including material quality, working environment, load and fastening force. In general, if correctly selected and rationally used, the service life of bolts and nuts can be as long as several years or even longer. Here are some suggestions for extending the service life of bolts and nuts: Choose high-quality materials: Use bolts and nuts with high strength and corrosion resistance to ensure good durability. Proper installation and fastening: Follow proper installation instructions to ensure that bolts and nuts are properly installed and fastened. Too loose or too tight fastening force will have an adverse effect on the service life. Regular maintenance: Check the condition of bolts and nuts regularly to find and repair any damaged or tired parts in a timely manner. This will prevent further damage. Prevent corrosion: Keep the environment dry and use anti-corrosion coatings or materials that are not easy to rust when needed. This can effectively reduce the impact of corrosion on bolts and nuts. Reasonable design load: Ensure that the designed load is within the range that the bolts and nuts can bear, to avoid exceeding their rated load. Periodically test the fastening force: test and adjust the fastening force by appropriate methods as required to ensure that the bolts and nuts are properly fastened during the working process. Please note that under special working conditions, such as high temperature, vibration, vibration and other environmental conditions, the service life of bolts and nuts may be more challenged. In this case, it is necessary to pay closer attention to and maintain the condition of bolts and nuts to ensure their safe and reliable work.
