Prime-Line 9057170 Hex Lag Screws, 1/2 In. X 6 In., A307 Grade A Hot Dip Galvanized Steel (25 Pack)

The "Deep Wood Screw" is a heavy-duty solution for applications where standard wood screws cannot support the load.

With deep threads and a 6-sided hex bolt head, this screw requires a pilot hole to be drilled before installation.

Despite its size, it does not accept a nut, making it ideal for deck building and other structural projects.

Meeting ASME B18.2.1 and ASTM A307A specifications, this screw is built to last and perform under heavy loads.

Whether you're a seasoned carpenter or a DIY enthusiast, the "Deep Wood Screw" is the perfect choice for any project that requires strength and durability.
