The complementary mechanism of spring lock washers and thread adhesive

When spring lock washers and thread adhesive are used together, the anti-loosening mechanisms of the two can complement each other to form a more reliable anti-loosening solution:
Mechanical and chemical dual protection: The spring lock washer provides a mechanical anti-loosening effect through its elasticity, offsetting part of the loosening tendency caused by vibration or thermal expansion, while the thread adhesive fills the thread gap through chemical bonding, further preventing the bolt from rotating and loose. The synergistic effect of the two can significantly improve the anti-loosening effect, and is suitable for use in high-vibration and high-impact environments, such as aviation, automobiles, and heavy machinery industries.

Avoid fatigue and deformation issues: Under long-term vibration or stress cycling conditions, spring lock washers alone may fail due to fatigue or creep, while the chemical bonding effect of thread glue is not affected by mechanical fatigue. Therefore, thread glue can effectively compensate for the fatigue problems that may occur in spring washers during long-term use and extend the life of the entire fastening system.

Improve sealing and anti-corrosion performance: The bonding layer formed by the thread glue after curing can not only prevent the thread from loosening, but also act as a seal to prevent the penetration of liquids, gases and corrosive substances. In combination with spring lock washers, the corrosion resistance of fasteners can be significantly improved, especially in humid or corrosive environments such as the marine engineering or chemical industries.
