Nylon Insert Lock Nut

Product Code: MD-CVT-0011

A DIN 985 lock nut contains a polymer ring in its upper section. As the bolt passes through the insert, friction resists unintentional rotation caused by vibration or impact. ## Function - Helps retain structural and mechanical joints. - Used on vibrating machinery, vehicles and equipment. - Suitable for outdoor or humid service when the correct material is selected. - Applicable in construction, bridges, wind turbines, buildings and automotive assemblies. ## Installation 1. Start the metal side of the nut squarely on the bolt thread. 2. Advance it until the polymer insert engages the thread. 3. Tighten with the correct tool without exceeding the specified torque. 4. Check that the nut is fully seated and the joint has no play.
