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.

Spring Lock Washers for Plastic Screws
Designed for use with plastic screws, these acetal washers are good electrical insulators. They are excellent for use under water and in rotating assemblies. Their slightly cupped shape gives them spring-like flexibility to grip joints tighter than split and tooth lock washers.
