Din 982 Nylook Nut

A Nylock nut is a specialized type of lock nut featuring a nylon collar insert that effectively resists loosening. The nylon insert, positioned at the top of the nut, is slightly smaller than the major diameter of the screw, creating a tight grip when the nut is tightened. As the nut is fastened, the nylon insert deforms elastically, securely gripping the bolt threads. This design provides significant resistance to loosening caused by vibration and torque, making Nylock nuts ideal for applications where maintaining a secure connection is critical, especially in dynamic or high-vibration environments.
