contro/grain grain

Hello everyone
question maybe scema. how to use the nut + against/dado for the blockages, would it be correct to use the grain plus a counter/grain in the blocks of trees or anything else to prevent it from spontaneously?

in the past it was done, now with modern brakings and various blockers is an unused technique.
Also because it requires attention, the superior grain if tightened too strong risks to damage the lower one making it difficult to unscrew.

with the brakes however it is quite definitive as locking

no, braking is always removable, to block "definitely" there are blockers, of various type.
the more "debula" allow a disassembly, even if difficult, the strong ones do not.
even if then heating well you can remove it even if blocked with strong blocker.

Wheat and against grain is practically spread especially for the use indicated in your figure. use tip grains and medium or light brakings. remains the footprint and the grain does not return.

thanks to all

based on the application, it could be even better to use a northern-lock washer with simple nut.

you can also lubricate the joint, avoid the grip, have + control on the torque / preload and therefore more safety and precision in the tightening
