Hillman 5/16 in. Dia. Stainless Steel Split Lock Washer 100 pk

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 18-8 stainless steel finish offers good corrosion resistance. Use with treated lumber in applications with like nuts and bolts of similar diameter. *
