This all-metal self-locking hex nut is manufactured to DIN 980V and ISO 7042 standards. Its built-in locking mechanism helps prevent the nut from working loose under vibration or mechanical stress. Made from grade 8 steel, it's designed to pair with bolts and screws of property class 8.8 or lower, and features a metric thread. The electro-galvanized finish makes it ideal for indoor applications or environments with minimal exposure to the elements.
