Thread-Forming Flange Locknuts
These nylon flange locknuts form threads as they're tightened to resist vibration. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. They're not reusable. Made from nylon 6/6, they're chemical resistant, nonconductive, and lightweight. Height includes the flange.
