Din 985 Nylock Nut

The DIN 985 Nylock Nut, also known as a nylon-insert lock nut, is a specialized hexagonal nut designed to prevent loosening. It features a nylon collar insert located at the end of the nut. This nylon insert is intentionally smaller in diameter than the nut itself, which causes it to deform elastically when the nut is tightened onto a bolt. This deformation creates a tight grip on the bolt threads, offering effective resistance to loosening, particularly in high-vibration environments. The DIN 985 Nylock Nut is ideal for applications where maintaining a secure connection is critical despite dynamic forces.
