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. Zinc plated fasteners are the most common used plating. This ensures good rust-resisting qualities, appearance and low cost.
