This self-locking hex nut, also known as a lock nut, features a nylon insert that acts as a non-metallic locking element. This built-in design minimizes the risk of the nut loosening due to vibration or mechanical stress. Manufactured to DIN 985 and ISO 10511 standards, the nut is made from D6 stainless steel (1.4462) and comes with a metric thread.
