1. Nylon-insert lock nut, polymer insert lock nut, or elastic stop nut, is a kind of locknut.
2. It is a nut with a nylon insert that resists turning.
3. The plastic insert is placed at the end of the nut, and its inner diameter (ID) is slightly smaller than the diameter of the screw.
4. The inserts deform elastically over the threads of the screw, but threads are not cut into the nylon.
5. The flange design allows the nut to span larger holes than a standard nylon insert stop nut.
