This all-metal self-locking hex nut is manufactured to DIN 980-V and ISO 7042 standards. Made from grade 10 steel, it's designed to pair with bolts and screws up to property class 10.9. The nut features a zinc flake coating (Cr(VI)-free, ISO 10683 flZnnc 10)—a zinc-aluminum blend that delivers superior corrosion resistance compared to a pure zinc coating of the same thickness. There's no risk of hydrogen embrittlement, and the nut comes with a metric thread.
