What many people often underestimate is the need for a locknut, and the fact that not all locknuts can be used for the same purpose.
The most well-known locknut is the one with a nylon locking system, also used by Volkswagen here and there, but it cannot be used for all purposes.
The locknut mentioned here is not only passivated in green to protect it from corrosion, but more importantly it is made of a composite material, which is a mixture of synthetic resin and carbon fiber. This makes the locknut suitable, among other things, for assembling parts that do not need to be tightened all the way and are not likely to come loose in any situation, and for securing very critical parts.
Volkswagen has used this lock nut in the situations described below and it should not be replaced with a lock nut with a nylon locking device or any other type of locking device. Once loosened, it must be replaced. Correct securing can then no longer be guaranteed. The number indicated indicates how many are needed if you have to replace them all.
Beetle:
-Tighten the locking plate of the steering bar support 1303 from 8.1974 (1 piece)
Bay Window Bus:

* Original Volkswagen cap nuts were used with locking, which were then converted to the replacement nuts shown here. Not as Volkswagen applied it in the factory, but the nut that Volkswagen later designated as a replacement nut.
