What Are Nylon Insert Lock Hex Nuts (DIN 985)?
A DIN 985 nylon lock nut achieves a locking effect through its nylon insert, which grips the bolt thread as tightening progresses. This prevailing torque helps prevent the nut from backing off under vibration or movement, reducing the need for additional locking washers or chemical threadlock in many assemblies.
