Kako rešiti razrahljanje kombiniranih vijakov po namestitvi?

Increase friction

Replace the washer: You can replace the original washer with a washer with greater friction. For example, a spring washer is like a small spring. When tightening the combination screw, the spring washer will be compressed, generating elastic force, increasing the friction between the screw and the connected object to prevent loosening.

Apply thread glue: Apply some thread glue on the threads of the combination screw. Thread glue is like glue, which can stick the screw and the connected object together and increase the friction between them. After the thread glue dries, the screw will be fixed more firmly.

Retighten

Use the right tool: Use the right screwdriver or wrench to retighten the combination screw in the correct direction. Just like we tighten the faucet, we need to use force but not too much, otherwise the screw may be broken.

Control the tightening force: To control the tightening force, it should not be too loose or too tight. Too loose will still loosen, too tight may damage the screw or the connected object. You can refer to the specifications of the combination screw and tighten it according to the above requirements.

Replace the combination screws

Check the damage: If the combination screws are damaged, such as thread wear and head deformation, then you need to replace them with new combination screws. Just like our shoes are broken and uncomfortable to wear, we have to change a new pair.

Choose the appropriate specifications: When replacing, choose combination screws with the same specifications as the original ones to ensure the installation effect.

Add auxiliary fixation

Use nuts: Add a nut to the other end of the combination screw and tighten it. The nut is like a "little helper" that can work with the combination screw to fix the connected object more firmly.

Add a gasket: Add a suitable gasket between the connected object and the combination screw to increase the contact area and friction, and also prevent loosening.
