Detailed Information

DIN 267 Part 4 was converted to the international property classes for nuts in 1967. The previous symbols 4D, 5D,
5S, 6G, 6S and 8G were replaced by code numbers 4, 5, 6, 8, 10, 12 and 14 where the code number indicated 1/100 of
the minimum tensile strength of the bolt with which the nut could be mated and loaded up to the minimum tensile
strength of the bolt, e.g. bolt 10.9 — nut 10. Appropriate proof load values were allocated to the nuts.
