Product description

M7 nuts are not very common and certainly not with a hardness class 10. On our classic Volkswagens, they are mainly used in the gearbox and on type 4 engines, the rocker shafts are fixed with these nuts. The fact that a hardness class of 10 is used for these applications is not by chance.

Unfortunately, we still regularly find that standard M7 nuts are used. The nuts must continue to function under all circumstances, a standard M7 nut is not suitable for this, it will sooner or later lead to problems.

If a galvanized nut has been used, you can assume that it is not a class 10 nut. Don't take any chances and replace it with a class 10 steel nut.
