Engineered to provide more uniform load distribution, split lock washers are great for any indoor and outdoor project. Ideal for situations where potential loosening from corrosion or vibration is a concern, split lock washers are used to prevent nuts and bolts from coming loose. These grade 8 fasteners contain split ends that help lock into the mating material, thus providing a locking feature when tightened beneath a nut. The yellow dichromate zinc plating provides moderate corrosion resistance. Use with treated lumber in applications with like nuts and bolts of similar diameter.
- Commonly used in applications using a bolt or a screw where two pieces are being joined together
- Split ends grip the material surface to prevent loosening during vibration
- Hardened with a yellow dichromate finish for corrosion resistance
