Shipping Details

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.

Features a SawTooth point design, which provides fast starts and no predrilling or separate washer needed
Burly 0.276-in shank diameter ideally suited for heavy-duty structural applications
3/8-in hex drive for secure driving
Oversized 0.93-in integral washer eliminates the need for a separate washer
Length: 6-in
ASTM A153 Class-C hot-dip galvanized coating suitable for coastal and marine environments
For best results, use a minimum of 1/2-in low-speed corded drill to install
