Abstract
A fastener-washer combination for securing a thin workpiece to a support member includes a fastener having a head and shank portion connected through a bugle shaped intermediate section which smoothly blends into the shank. A resilient washer frictionally engages the shaft and is adapted to interact with the bugle shaped section as the fastener is driven into the workpiece.
