This all-metal self-locking hex nut, manufactured to DIN 980-V and ISO 7042 standards, features a built-in locking mechanism that helps prevent loosening caused by 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. The nut has metric threading and a zinc-plated, yellow-passivated finish, making it well suited for indoor applications or environments with minimal exposure to the elements.
