Manufactured with undersized thread in tolerance class 6AZ (thread play) before surface protection is applied (DIN EN ISO 10684).

The bolts are ISO-compliant after hot-dip galvanisation.

The bolts must not be used with nuts that have an oversized thread. This can create problems in the bolted joint and may cause the connection to fail.

Notice

ISO 4017 replaces DIN 933 | There is some similarity | Nominal size extended | Width across flats for M10, M12, M14 and M22 changed.
