This self-locking hex nut with a nylon insert is manufactured to DIN 985 standards and features a non-metallic locking element that reduces the risk of the nut loosening due to vibration or mechanical stress. Made from stainless steel (A2), the nut comes with a metric thread. Thanks to its LUBRINOX® finish, it's engineered to prevent thread galling (cold welding or seizing)—a common issue with standard stainless steel fasteners.
