Why do stainless machine screws come loose when they are tightened for a long time?

The material will expand and contract in heat and there will be vibration at the screw connection. The reason why the screw will come loose after being tightened for a long time is that the vibration usually occurs during the working process and the working pressure changes, which may lead to the deformation of the stainless machine screws. Causing the screw path to loosen.

The solution is: one is the usual stainless machine screws has self-locking function, generally under the static load is not loosened, generally add a pre-tightening spring gasket to ensure the fastening state, so can increase the contact pressure to increase friction. That way it won’t come loose easily.

Second, screw glue, stainless machine screws can be effectively bonded to prevent loosening.

The third is a regular inspection. If it is loose, tighten it in time.
