Engineered to provide more uniform load distribution, split lock washers are great for any indoor/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. *
