The H100-ESN self-locking hex nut features a built-in locking mechanism designed to prevent loosening from vibration or mechanical stress. Made from electro-galvanized steel, it's ideal for indoor use or applications with minimal environmental exposure. Rated at strength class 8, this nut pairs perfectly with bolts and screws of strength class 8.8 or lower, and comes with a metric thread. Built to withstand temperatures ranging from -50°C to +300°C, it can be reused up to five times with no noticeable drop in performance. Thanks to the centrally positioned locking slot, the nut is fully reversible and well-suited for automated assembly.
