Description
The washer on these screws has sharp external teeth that dig into surfaces for maximum holding power and vibration resistance. Also known as Sems screws, the washer rotates freely but is permanently attached. They have a zinc plating that provides corrosion resistance in wet environments. Length is measured from under the head.
