811062 Split Lock Washer, 5/8 in ID, Hot-Dipped Galvanized

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 fasteners contain split ends that help lock into the mating material, thus providing a locking feature when tightened beneath a nut. The hot-dipped galvanized finish provides superior corrosion resistance. Use with treated lumber in applications with like nuts and bolts of similar diameter.
