  What WEIGAO will share with you in this issue is how to prevent the hexagon flange bolt from loosening? Hope that you have a new understanding of hexagon flange bolt after reading!

  NO.1 friction anti-loose method

  This is a widely used anti-loosening method. This method produces a positive pressure between the thread pairs that do not follow the external force to produce a friction force that can restrain the relative rotation of the thread pairs. This positive pressure can be achieved by pressing the thread pair axially or simultaneously in two directions.

  NO.2 Anti-loose method

  Spot welding, riveting, bonding, etc. In this method, most of the threaded fasteners are crushed during disassembly and cannot be reused.

  O.3 Riveting and anti-loose method

  After tightening, the outer hexagon flange bolt adopts methods such as punching, welding, bonding, etc., so that the thread pair loses the characteristics of the movable pair and the connection becomes impossible to disconnect. The disadvantage of this method is that the bolt can only be used once, and the disassembly is very difficult, and the bolt pair must be crushed to be disassembled.

  NO.4 Mechanical anti-loose method

  Use split pins, stop washers, and string wire ropes. The method of mechanical anti-loosening is more reliable, and the method of mechanical anti-loosening should be used to deal with important connections.

  NO.5 structure anti-loose method

  The anti-loose structure does not rely on manpower outside the circle, but on its structure. The structural anti-loosening method, namely the Down's thread anti-loosening method, is also the anti-loosening method that has begun to advance and results, but it is not known to most people.
