A nyloc nut, also referred to as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut, is a kind of locknut with a nylon collar that increases friction on the screw thread. Black Japan is a lacquer or varnish suitable for many substrates but known especially for its use on iron and steel. Its high bitumen content provides a protective finish that is durable and dries quickly.
