  • Nylock machine screws with washers are specialized fasteners that provide a secure hold.
  • Their threads have been carefully angled to ensure that, once they are screwed in, they will not slip, move, or come loose without additional force.
  • This makes them perfect for applications needing something to stay in place.
  • Unlike standard screws, Nylock machine screws with washers require extra effort to be removed, even when the correct tool is employed.
