Power Pro®Premium Exterior Wood Screws are designed for deck building and exterior wood projects These exterior wood screws are engineered to make fastening solutions easier and reduce call-backs. The unique thread design and self-starting tip help to provide faster engagement into wood, less wood splitting than standard wood screws and a 30% faster installation time from start to finish. The star drive increases the number of contact points to virtually eliminate cam-out during installation. Countersinking blades clean out wood debris and enable a clean and secure finish, while the no-split twist shank reduces the likelihood of splitting wood. Hillman’s patented Bore-Fast™ thread drives 30% faster without pre-drilling.
