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.
