Product Description

The Strong-Drive SDWH Timber-Hex HDG screw is a hot-dip galvanized fastener suitable for heavy-duty marine and coastal applications. It's ideal for use in structural pilings, piers, docks, boardwalks and offers the lowest installed cost for comparable pile solutions on the market. No longer do you need to purchase expensive auger drill bits, separate washers, nuts or bolts. Installation time is faster because you install only from one side and no predrilling is required.
