About the 1952935 Hex Lock Nut M2, DIN 985
This item is a hexagon lock nut referenced to DIN 985 in thread size M2, property class 6, with a blue-passivated zinc-plated finish, as designated in the product name. DIN 985 is the long-established German standard for hexagon thin lock nuts with a non-metallic insert: a polyamide ring is captive in the top of the nut and deforms around the mating thread as the nut is run down, resisting rotation loosening under vibration without damaging the bolt thread. Property class 6 is the strength class marking for the nut, and the zinc plating with blue passivation provides corrosion protection for general indoor and light-duty service. The reference 1952935 is the catalogue part number under which this nut is listed; at M2 it sits at the small end of the metric lock-nut range.
