WSK M06 B3 1984r The nut is made very aesthetically. Model threads - fit at the highest level. Coating is also very good. The price is a bit discouraging.
Very good product, but not everything went in without a little resistance the only problem I encountered was the connection of the pipe with the shelf the jlement is a little too thick so I had to grind to enter the washer to the bearing the rest in the best possible order:)
