Din 985 Nyloack Nut

The DIN 985 Nylock Nut, also known as a nylon-insert lock nut, is a specific type of hexagonal nut that features a nylon collar insert to prevent loosening. A Nylock nut is a hexagonal nut with a nylon collar insert at its end. The nylon insert is slightly smaller in diameter than the nut, causing it to deform elastically when the nut is tightened onto a bolt. This deformation provides resistance to loosening, making it effective in high-vibration environments.
