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 fasteners contain split ends that help "lock" into the mating material, thus providing a locking feature when tightened beneath a nut. Use with treated lumber in applications with like nuts and bolts of similar diameter.
Special black chromate plating provides corrosion resistance and durability
Used in applications with nuts and bolts of similar size and finish
Prevents loosening during vibration
Commonly used in applications using a bolt or a screw where two pieces are being joined together
