This nylon-insert lock nut features a non-metallic locking element that helps prevent the nut from loosening due to vibration or mechanical stress. Manufactured to DIN 6924 and ISO 7040 standards, it's rated at property class 10 and is compatible with bolts and screws up to grade 10.9. Made from steel with an electrolytically zinc-plated finish, it's designed for indoor applications or environments with minimal exposure to the elements. The nut comes with a metric fine thread.
