Dewalt, Baltimore, is offering construction workers a chance to win $1 million and a new Chevy Silverado pick-up truck in its Million Dollar Challenge cordless screwdriving contest. From March through August the company is staging more than 500 local qualifying contests across 100 cities throughout the U.S. and Canada.

The challenge is to sink five drywall screws flush into a wooden board as fast as you can using a Dewalt cordless drill. The fastest local winners earn prizes and move on to one of 14 regional events. The top 14 contestants advance to the final tournament in November at the Phoenix International Raceway.
