Lock washers known as split lock washers place tension against a nut after tightening, to help prevent the nut from loosening. They provide a more uniform load distribution, and are great for any indoor/outdoor project. Ideal for situations where potential loosening from corrosion or vibration is a concern. Lock washers provide a locking spring action and are used to prevent nuts and bolts from coming loose from vibrations. They have split ends that help "lock" into the mating material, thus providing a locking feature when tightened beneath a nut. Steel is zinc plated for moderate protection against rust. Use hot dipped galvanized finish or stainless steel where corrorsion and rust is of concern or in exterior projects.
Internal Tooth Lock Washers bite into the screw head while the smooth, outside rim won't snag objects. Provide greater vibration resistance than split lock washers. Used with fasteners that have small heads. Zinc-plated steel washers are corrosion resistant in wet environments.
