How does the turnlock assembly Stainless steel 316 work?


For a turnlock assembly to work as it should, there needs to be a spring effect in the assembly, either in the stud or receptacle.

Since the stud has no belleville washers, there is no spring effect in this assembly.

In order to gain the functionality of the spring effect, the customer himself will need to add 1 supplementary piece to the assembly so the assembly has the desired spring effect.

For example, the customer can add a gasket, which is thick enough, or another piece that can create the spring effect.
