Metric Steel Pan Head Screws with Split Lock Washer
When compressed, the split lock washer flattens to add tension and prevent loosening from small amounts of vibration. Also known as Sems screws, the washer rotates freely but is permanently attached. A zinc plating provides corrosion resistance in wet environments. Length is measured from under the head.
