1
Buffering EffectIn the process of mechanical operation, due to vibration, impact or temperature changes and other reasons, the cushioning effect of the elastic pad and the flat pad can effectively reduce the problems of loose screws or deformation of connecting parts, thus increasing the reliability of the connection.
-
2
Locking ActionThe bolt-spring pad and the flat pad can lock the position of the connecting part, keep it in the correct position, and prevent movement due to external force, ensuring the tightness and stability of the connection.

Reduce Connection Component DamageConnecting components bearing screw connections often produce stress. The bolt plus elastic pad and flat pad can bear these stresses, lighten the load of the connecting parts, thus avoiding damage to the connecting parts.
