Problems solved by technology

Ships, vehicles, water conservancy projects, etc., the existing bolts and nuts are usually designed with spirals. In order to prevent the bolts from loosening, they are often used in combination with anti-loosening washers or nuts. During their use, manual rotation is required. , first install the nuts to a suitable position, and then tighten the bolts, which is inconvenient to use and takes man-hours. There are some electric tools on the market that can drive the tightening of the bolts through the motor, but they can only tighten the bolts. For pads The nut lining the inside of the bolt cannot be tightened due to structural limitations, and still cannot get rid of the limitation of manual work
