Clear plastic hex nut and plastic washer on the outside with a gold-colored metal nut inside
Plastic nuts and washers help eliminate the loosening of eyeglass screws and nuts on your rimless eyeglasses. They are easy to work with and won't loosen up.
The plastic nut encapsulates a metal nut, and has a built-in plastic washer that will not scratch your eyeglass lens. The bearing surface of the plastic nut and washer helps retain the torque, the metal nut inside resists stripping out the threads.
